THE DIFFICULT HISTORY OF DAVIDIA INVOLUCRATA - Handkerchief tree or Dove tree

To begin with, the history of the introduction of Davidia involucrata is arguably as difficult as the tree is beautiful. Commonly known in England as the Handkerchief tree, it was first discovered for the western world by the French Missionary Father Armand David (1826–1900). As a biologist from University of Espelette, Père David entered and became ordained through the Congregatio Missionis, a Roman Catholic society of apostolic life of priests and brothers founded by Vincent de Paul.

Father Armand David
Shortly after his ordination the Mission sent him to Beijing where on his own accord began to create a selection of Zoological and botanical material for a Museum of Natural History. However at the request of the French Government be began to send specimens back to the Jardin des Plantes, Paris - the main botanical garden in France, of which the best of the specimens caused quite a stir. To gain greater knowledge the Jardin des Plantes commissioned Père David to send back further plant collections from China.

In 1869 Père David discovered a single specimen of Davidia involucrata growing at over 2,000 metres altitude (a height usually beyond the treeline), and later sent dried specimens to Paris in 1871. The unique and unusual pendulous white blooms caused quite a sensation and after further investigation it was declared both a new species and genus, and was subsequently named in honour of Father Armand David.

News of this exotic new tree reached London and inevitably the ears of Sir Harry Veitch of Veitch Nursery, Chelsea, but while the whereabouts of Davidia involucrata were unknown, his passion to find and retrieve specimens for his nursery had been ignited.

Move forward 10 years to 1881 and still nothing further had been heard regarding Davidia involucrata. However all that was to change when Irish plant hunter Augustine Henry (who at the time was working for the Imperial Customs Service in Shanghai as Assistant Medical Officer and Customs Assistant) began sending back specimens to Royal Kew gardens. Like Père David before him, Henry found a single tree, this time in the Yangtse Ichang gorges, and sent the first dried specimens back to Kew Gardens.

Sixteen years later in 1897,  arguably the most famous of all plant hunters Ernest Henry "Chinese" Wilson began work at the Royal Botanic Gardens, Kew. He had already began to make a name for himself by winning the the Hooker Prize for an essay on conifers and quickly came to the attention of Sir Harry Veitch who offered him a position as Chinese plant collector. By now Davidia involucrata had become legendary and Sir Harry who were eager above all to retrieve live examples from which to propagate. Sir Harry had one piece of clear advice for Wilson

"Stick to the one thing you are after, and don't spend time and money wandering about"

With hundreds of plant hunters on his books and thousands of Chinese specimens returning to the Veitch nursery every year Sir Harry believed that probably every worthwhile plant in China had been introduced to Europe.

So Wilson travelled west towards China, following Augustine Henry to Simao where he was investigating plants used in Chinese medicine. Henry detailed the area where he has seen his specimen 12 years earlier but as luck would have it the tree had been recently cut down for building purposes by the time Wilson reached it.

Completely ignoring the advice of Sir Harry, Wilson managed to rediscover the specimens originally found by Père David a staggering 600 km away back in Yichang, Hubei. There he found a grove of the trees overhanging a sheer drop from which he collected his fabled specimens. Wilson collected for a further two years in Hubei Province before returning to England in April 1902. Upon his return Wilson had his boat wrecked, but despite this managed to save his Davidia specimens and finally hand this precious cargo to Sir Harry Veitch. The rest is history.

GROWING YOUR OWN FOOD FROM SEED



You do not have to live on a farm to know, vegetables that you grow yourself from seed just taste better. Your vegetables are filled with the good nutrition you want and are spared the harmful chemicals that commercial plants are exposed to.


In this post, we are going to give you some tips to grow your food from seeds. Once you see how easy it can be and experience the fresh tastes of your harvest, you will never go back to grocery store produce.



It starts with quality seeds

The seeds you plant are critical to the success of your vegetable garden. Buying seed from a discount store, or a chain department stores is not always a good choice. You do not know if the seed is a high-quality product. You do not know how long and under what conditions the seed has been stored.


Seed Needs is an industry leader in vegetable and flower seeds. Their experts can answer your questions and help you select the seed that will grow best in your area. You get good-grade seed at good prices.

The size of your garden

You do not have to have a huge area to plant a garden. You can begin your plants in containers and then transplant them to a raised garden bed. More important than size is the quality of the garden. A 10X10 garden that is healthy and weed-free is much more productive than a 25X50 garden that is continually under attack from weeds and insects. The main thing is to plant where your plants can get 6 to 8-hours of direct sunlight per day. This will help your soil stay temperature controlled and healthy. If you have areas that are shaded, use those areas to plant leafy vegetables like lettuce and spinach. Peas will also grow well in shady spots.


Also, keep in mind that during dry spells, you will need to water your plants. Watering and harvesting are easier if you plant your garden close to your home.

Soil

The soil you plant in is just as important as the seed you use. Whether you have a container garden, a raised garden, or a traditional in-ground garden, the soil must be moist and well-drained.


Organic matter is best for fertilizing your plants. Compost, peat moss, or manure are good choices for fertilizer. You will also want to invest in a soil thermometer so you can track the temperature of the soil. As you gain experience, this will come naturally to you. But in the beginning, a thermometer is a valuable tool.

How many plants do you need?

If you are a beginner gardener, this is a common question. Many new gardeners plant too many warm-season plants such as tomatoes, peppers, and squash. You need to determine how much of these vegetables your family can eat and how much your garden will produce. For example, one healthy tomato plant will produce about 10 pounds of tomatoes in a season.

Now is the time

Early spring is right for planting most warm-weather veggies. If you are starting your plants indoors, just be sure the threat of frost is over before you transplant them. While you are planting, don’t forget to order some herb seeds. Herbs are easy to grow indoors or out, and there is nothing that makes your fresh veggies taste better than home-grown herbs.

Conclusion

Planting your garden is not difficult. The benefit you get from having fresh food is remarkable. Order your seeds now for your April and May planting.

CHAND BAORI STEPWELL

The steps and pavilion inside the Chand Baori stepwell
Inside the Chand Baori stepwell



The Chand Baori stepwell is a stunning example of Indian architecture and is one of the oldest and most ornamental sites of interest in Rajasthan. Built within the village of Abhaneri (originally named Abha Nagri meaning 'City of Brightness'), the Chand Baori stepwell was constructed in AD 800 and at approximately 30 metres deep it is both one of the largest as well as one of the deepest stepwells in the whole of India.

The pavilion of the Chand Baori stepwell.
The pavilion of the Chand Baori stepwell 
The state of Rajasthan is the largest in India and is well known for its arid and infertile climate, particularly in the region of Abha Nagri. To conserve as much water as possible the Baori (meaning well) was built by King Chanda (hence the name of the well) of the Nikumbh dynasty between 800 CE and 900 CE. The stepwell is located opposite Harshat Mata Temple and was indeed dedicated to Harshat Mata, Goddess of Joy and Happiness upon its completion.

Chand Baori consists of 3,500 narrow steps over 13 stories, and at the base of the well, the air remains a consistent 5-6 degrees cooler than that of the surface. As you would expect the Chand Baori stepwell was used as a community gathering place for locals during periods of intense heat.

Corridor containing artefacts inside the Chand Baori stepwell
Chand Baori stepwell corridor
It is square on plan with the entrance facing north. On three sides the well has double flights of steps, while the northern side consists of a multi-storeyed corridor supported on pillars and projecting balconies which enshrine some gorgeous images of Mahishasurmardini (a buffalo demon in Hindu mythology) and Ganesha (the elephant god). The pavilion and resting room were built for use by royalty only. The surrounding cloisters and entrance pavilion were later editions.

Sadly, today there is no evidence of the old city surrounding the Chand Baori well, only beggars, street traders and stray dogs line the ancient street. This means the site is out of context to its former glory and literally appears to be in the middle of nowhere. The being said, it is a truly beautiful site and well worth making a detour from you journey.

Artifacts from the Chand Baori stepwell

For those who are interested in such things, Chand Baori is also a popular film location. So you can revisit the stepwell in the Best Exotic Marigold Hotel, The Fall and The Dark Knight Rises amongst others.

WANT TO BUY BLACK BANANA SEEDS? THEN CLICK HERE FOR OUR EBAY SEED SHOP

The original species of what is commonly known as the Thai Black Banana - Musa balbisiana, is a species native to eastern South Asia, northern Southeast Asia, and southern China. It is considered to be an inedible form due to the large amount of seeds within its fruit, however it is generally believed to have been part of the diet of local inhabitants as (along with Musa acuminata) it was used in the cultivation of one of the ancestors of modern cultivated bananas. It was first described for western science in 1820 by the Italian botanist Luigi Aloysius Colla (1766 –  1848)

Musa Balbisiana 'Atia Black' is a clump forming cultivar which under favourable conditions can reach a height of 5 metres. It has an upright habit and is particularly noted for its very striking dark stems and dark-green paddle-shaped leaves. When exposed to direct sunlight the stems darken further to almost black! Where conditions are suitable you can expect red to maroon to emerge which once pollinated are followed by large, blue to green coloured fruits.

How to grow Musa balbisiana 'Atia Black'

When growing in the cooler climates of northern Europe plant in a sheltered position which will receive as much sunlight throughout the day as possible. It will perform best in a rich, moist, well-drained soil. Additional watering will be required during periods of drought and a liquid fertiliser can be applied every week or so. Surprisingly it is arguably one of the most cold-hardy banana cultivars capable of tolerating frosts. If winter protection in required, cut of all the leaves to the crown and wrap in a dry mulch (such as straw or hay) and secure with chicken wire. In fact there is anecdotal evidence that the root system of Musa Balbisiana 'Atia Black' can survive temperatures down to as low as -9 degrees Celsius.

In the milder climates a couple of layers of horticultural fleece will be suffice in all but the severest winters. Just remember that the leaves will still need to be removed to reduce the incidence of fungal rots taking hold.

To limit its size you can grow Musa Balbisiana 'Atia Black' as a container plant using as large a pot as you can effectively move with causing injury to yourself. Use a good quality compost such as John Innes 'No. 3', watering and fertilizing regularly over the growing period. As it is no longer in the ground the root system will be at a greater risk of freezing if left outside during harsh winters and so bring it in under protection until the risk of late frosts have passed.

HOW TO GROW MUSA SIKKIMENSIS FROM SEED

Botanical specimen of Musa sikimensis in Quarryhill Botanical Garden, Glen Ellen, California, USA.




Commonly known as the Darjeeling Banana, Musa sikkimensis is one of the most popular of all the ornamental forms within the genus, as well as being one of the most widely cultivated. While the true species displays yellow-green foliage like most other banana plants, they are an number of stunning colour morphs which place cultivars such as Musa Sikkimensis 'Red Tiger'.

Young purple striped green leaves of Musa sikkimensis 'Red Tiger'
Musa sikkimensis 'Red Tiger'
Native to both Bhutan and India, Musa sikkimensis is one of the highest altitude banana species. This has benefits for UK gardeners as it is arguably the hardiest species behind Musa basjoo and Ensete lasiocarpa.

Seed is relatively easy find in both good plant retailers and online seed specialists, just buy as fresh as you can to achieve the best rates of germination.

Before sowing your seeds soak for 24 hours in warm water. Then using a seed tray or large modular tray, fill with a good quality seed compost such as John Innes ‘Seed and Potting’. Using a dibber sow the Musa Sikkimensis seed ¼in deep, then backfill the hole with a little more compost. Water thoroughly, but allow the excess water to drain away before placing the tray in a heated propagator or sealing inside a clear polythene bag and placing in a warm bright area. If using a heated propagator set the temperature of around 28 degrees Celsius. Be aware that the germination of Musa Sikkimensis can be slow and erratic taking between 1-6 months to germinate.

Keep the compost moist but not waterlogged and once germinated improve ventilation as fungal infections can take hold on both the foliage and the root system.

Once the root system has established the seedlings can be potted on into 9cm pots and allowed to grow on in a warm, frost free position. Water well during the growing season and feed with a liquid soluble fertiliser every couple of weeks.

THE CITRON - Citrus medica

Ripe citon fruits on the tree ready for picking
Citrus medica - The Citron


Widely known as the Citron, Citrus medica is one of just four original citrus species from which all other citrus types have been developed - either through natural hybridisation or selected cultivation. It has been grown since antiquity and as such its true origins are a little hazy. That being said it is generally believed to be native to Southeast Asia as uncultivated specimens can still be found here, although other wild examples have been found in India in the Western Ghats and the valleys at the foot of the Himalayas.

A species of citrus fruit (Citrus sarcodactylis Hort. Bog.): flowering and fruiting branch with separate numbered flower sections. Chromolithograph by P. De Pannemaeker, c. 1885,
The Buddha's hand of Citrus medica
The citron is a slow growing evergreen shrub or small tree, which under favourable conditions can attain a height of approximately 2 to 5 metres. It has an untidy open habit with glossy, ovate, lemon-scented leaves. However it is its large ornamental fruits which have made it a popular choice amongst gardeners. The citron's fruit shape can be highly variable due to the extreme thickness of the pith (otherwise known as albedo). Although not particularly palatable, the albedo is well established in the food industry as candied peel. The colour of the fruits ranges from green for unripe examples to a yellow-orange when overripe. You can't discuss the fruit of Citron medica without mentioning the Buddha's hand form - Citrus medica var. sarcodactylis. This is an unusually shaped variety with fruit segmented into finger-like appendages. These are said to resemble those seen on representations of Buddha. Depending upon the individual selection you can produce close hand or open hand forms. There are even half-fingered forms!

Like the majority of citrus plants, the citron is relatively easy to grow, In the United Kingdom, Citrus medica will not be hardy enough to grow outside permanently as it is easily damaged by even light frosts so it can only be grown as a pot grow conservatory specimen or in the ground as a greenhouse plant. That being said it will be fine growing outside over the summer once the threat of late frosts have passed. Plant into a good quality, soil-based, ericaceous compost, or produce you own by mixing peat-based ericaceous compost and John Innes No.3. It will require plenty of water over the growing season as well as a regular application of liquid soluble fertiliser.

HOW TO GROW WALLICHIA DISTICHA - The Fishtail Palm

How to grow Wallichia disticha



Native to the lowlands and montane rainforests of the Himalayas, India, Laos, Myanmar, Thailand, and Nepal, Wallichia disticha is just one of seven species within the genus named in honour of Danish botanist Nathaniel Wallich (1786-1854). The species name 'disticha' is derived from the Greek 'dis' and 'stichos' (meaning two lines), a reference to the two opposing rows of leaves. It is also the only species within the genus with this unusual leaf arrangement making it both a handsome and desirable species. The arching, pinnate leaves are approximately 2.4-4.5 metres long.

Commonly known as the False sugar palm, Wallichia disticha is a fishtail-like palm with a solitary trunk and large, stiff, feathery leaves which form from (usually) a single trunk. Under favourable conditions you can expect Wallichia disticha to reach an overall height of between 6-9 metres. The canopy is usually half that of the height. Specimens that are cultivated in dry or infertile soils will tend to produce smaller leaves and be smaller in height.

How to grow Wallichia disticha

How to grow Wallichia disticha
It is an easy to grow species that will perform best in a reliably moist sandy soil in full sun although it will tolerate half-shade in hotter climates. That being said it has proven to tolerate clay and loam soils which can also be slightly alkaline or acidic. Water during extended periods of drought, and improve drainage where necessary to prevent the roots becoming waterlogged over the winter as this cause the premature death of the plant. Feed with a liquid fertilizer rich in micronutrients (such as a liquid soluble seaweed-based fertiliser) to prevent nutrient deficiencies. Low levels of iron and magnesium can cause characteristic yellowing known as chlorosis. Micronutrient deficiencies are usually known to occur in acidic soils.

Wallichia disticha it is widely cultivated in subtropical and warm temperate regions and is surprising cold hardy capable of surviving freezing temperatures down to -2 degrees Celsius. Even colder temperatures can be survived if only for short periods. This means that it is possible to grow Wallichia disticha outside in the milder regions of Great Britain.

Once established avoid moving as the root system of this species is particularly sensitive to being dug up. This will often result in shocking the plant causing it to prematurely come into seed and then die.

Very little maintenance is required other than to remove any diseased, damaged or drying leaves, but do not prune until all of the leaf's green colour has disappeared.

HOW TO GROW THE TEA PLANT FROM SEED?

How to grow the tea plant from seed



Tea may no longer be the hot beverage of choice in England, but there are still approximately 165 million cups drunk within this emerald isle every single day.

A blend of Assam, Java, and Ceylon teas
How to grow the tea plant from seed
So with a nice hot cup of tea still up there across the nation why not consider growing your own tea plants and producing your own brew from freshly harvested leaves?

The botanical name for the tea plant is Camellia sinensis, the genus name of which will be familiar to most gardeners for its floriferous cousins.

Now despite popular images of Tea plants being picked in exotic, tropical locations, it is a surprisingly hardy species capable of surviving all but the harshest winters that the UK can throw at it.


How to grow tea from seed

First purchase 'as fresh as you can' tea seeds from a reputable seed supplier. Then before sowing, soak the seeds in tepid water for a day or so. Using a good quality, ericaceous, soil-based seed compost fill a large modular seed tray of 9 cm pots. Alternatively, create your own compost by mixing 50:50 John Innes 'Seed and Cutting' compost and Ericaceous compost. Press one seed into the centre of each pot or module with the eye of each seed facing upwards and cover with a thin layer or vermiculite, horticultural grade lime-free grit, perlite or compost.

Tea plant (Camellia sinensis) from Köhler's Medicinal Plants, 1897
How to grow the tea plant from seed
Gently water in and to help retain moisture, humidity as well as a warm rooting medium to encourage timely germination, place the tray or pots inside a heated propagator with a temperature at approximately 16-18 degrees Celsius. Alternatively, seal inside a clear polythene bag and place on a warm, bright windowsill, but out of direct of full sun. Water using a mister to keep the compost permanently moist but never allow it to become waterlogged. Tea seeds will germinate once overnight temperatures rise above 12 degrees Celsius, emerging from 4-6 weeks onwards.

Once germinated, remove the pot from the polythene bag or propagator. Modular sown tea seeds will need to remain until most of the seeds have germinated but you will need to keep an eye for fungal infections which can flourish in the warm humid conditions.

Once the roots have established in the modules they can be carefully lifted and potted on into 9 cm pots containing good quality soil-based ericaceous compost and moved into a protected environment such as an unheated greenhouse. Keep the compost moist and feed with an ericaceous liquid soluble fertiliser every week or two during the growing season. Once the plants have grown to approximately 30 cm high they will be ready for planting outside into their final position. However they must be acclimated to outdoor conditions over a couple of weeks by exposing them to direct sunshine beginning with one to two hours a day until they can withstand full sun

Tea plants will perform best in a sunny, sheltered position in sandy soil with a pH of 5 to 6.

HOW TO GROW THE SWEET BOX - Sarcococca confusa

Feuillage de Sarcococca confusa - Jardin botanique de Strasbourg - France
The 'Sweet Box' - Sarcococca confusa







The 'Sweet Box' - Sarcococca confusa may not be particularly eye-catching, but when you stroll past a specimen in full winters bloom it is undeniably nose-catching, if such a conjoined word exists! The common name is in reference to its similarity to the common box, Buxus sempervirens.

Under favourable conditions you can expect the sweet box to reach a mature height of 2 metres with a width of 1 metre. It is a compact, evergreen shrub with glossy, green, ovate leaves and a spreading habit. The origins of Sarcococca confusa are uncertain but it is generally believed to derive from China. Strangely it is not matched by any wild specimen, but there is some belief that it may have been raised from seeds collected by Ernest Henry 'Chinese' Wilson (1876 – 1930) in Western China. It was subsequently brought under cultivation in England around 1916.

The most notable feature of the sweet box is its highly fragrant, honey-scented blooms. The white flowers with cream-coloured anthers appear over the winter and once pollinated are followed by glossy, black berries 5 mm in diameter. In fact the genus name Sarcococca originates from the Greek meaning 'fleshy berry', referring to the fruit.

The sweet box is relatively easy to grow and will perform well when grow in moderately fertile, moist but well-drained humus-rich soil. It will perform best in shade as the foliage can bleach when exposed to full sun.. Semi-shade and full sun can be tolerated if the soil remains reliably moist during the growing period

It is also tolerant of atmospheric pollution, and once established will also be tolerant of drought and neglect. Like the true box - Buxus sempervirens, it is ideal for creating an informal low hedge.

Sarcococca confusa received the Award of Garden Merit in 1984.

HOW TO GROW TEA

Women picking tea leaves in a plantation of central Sri Lanka
How to grow tea 

If you are a keen gardener and love tea then you may be tempted to try and grow your own tea plant - Camellia sinensis, and process the leaf tips for your own consumption. While there are many Camellia species and cultivars familiar to British gardeners, Camellia sinensis is grown mainly in tropical and subtropical climates and as such is not considered hardy. That being said, some tea varieties are surprisingly cold hardy once established and have proven to shrug off all but the worst weather England has to offer. It is also tolerate of coastal climates. As such there are small, specialist tea plantations (using the 'Clonal One' cultivar) under cultivation in Cornwall in the United Kingdom, and rather surprisingly Perthshire in Scotland. You may be interested to know that Perthshire tea company 'The Wee Tea Company' won the honour of being the best tea in the world at the 'Salon de The' awards in Paris in 2015 for their Dalreoch smoked white tea!

A blend of Assam, Java, and Ceylon teas
How to grow tea
Tea plants are usually grown in regions which receive at least 125 cm of rainfall a year in rich, moist soil in full to part sun, so these conditions will need to be replicated as best as possible in the UK with the likelihood of winter protection required.

When left to their own devices, tea plants can reach a height of approximately 15 metres. However, for ease of harvesting, tea plants are usually kept to waist height. It takes 3-4 years for a newly planted tea plant to be established enough to cope with leaf harvesting. Under favourable conditions a tea plant will grow a new flush every seven to 15 days during the growing season. Leaves that are slow in development tend to produce a better-flavoured tea which is why Perthshire tea growers produce some of the best leaves in the world.

How to grow tea plants in containers

To keep it simple for cold protection, consider growing a tea plant in as large pot as you can comfortably move to a protected area when necessary. The key to successful cultivation is the rooting medium. It will need to be well-drained, moisture-retentive, slightly acidic compost. That can be achieved by mixing equal parts John Innes 'No3' compost, ericaceous compost and well-rotted farm manure and lime-free horticultural grit. It will perform best in full sun but will the compost must be kept moist at all times during the growing season to prevent the growing tips from drying out. That being said, do not allow the soil to become waterlogged as the roots can easily perish under this conditions.

Feed with a liquid soluble acidic fertilizer once every couple of weeks during the growing period.

Once temperatures look to start dropping below 7 degrees Celsius move your pot grown specimen to a frost free position such as an unheated greenhouse. Once spring temperatures rise, and the threat of late frosts have passed, your tea plant will need to be acclimatised for a week or two before being left outside in their final position.

How to grow a tea plant outside

Despite being associated with tropical and subtropical climates the tea plant is surprisingly robust in all by the worst of our British climate. However when cultivated for tea leaves the plant can be cropped more frequently and provide a better quality product when grown in favourable conditions. Ideally a south-facing, terraced hillside can provide the sunny aspect combined with good drainage, although irrigation may be required over the summer. Enrich the soil prior to planting with well-rotted farm manure and mulch every autumn taking care not to have the mulch touch the plants trunk.

HOW TO GROW THE TEA PLANT FROM SEED?

WHAT PLANT DO YOU GET TEA FROM?

English black Tea, a blend of Assam, Java, and Ceylon tea leaves
What plant do you get tea from?

If you are English then you are likely to have a strong emotional (and possibly addictive) relationship with tea. However besides from knowing that tea is made from an infusion of processed tea leaves then it is also likely that you will not know from which plant the tea leaves are from.

Botanical illustration of Camellia sinensis, the tea plant.
What plant do you get tea from?
The origins of tea date back so far into history that it is impossible to say when it was first drunk but records show that it was originally taken as a medicinal beverage in Southwest China approximately 3000 years ago, prior to it first becoming popular as a recreational drink during the Chinese Tang dynasty (618 - 907). Tea came to the attention of the English during the 17th century after being brought back to Europe in the 16th Century by Portuguese merchants.

The plant from which you get tea is called camellia sinensis, the genus name of which will be familiar to most gardeners. The traditional Chinese name for Camellia literally means 'Tea flower', while the wester name is in honour of Rev. Georg Kamel (1661–1706), pharmacist, and missionary to the Philippines and who incidentally did not discover or name this plant, or any other Camellia species. The species name 'sinensis' is Latin for 'from China'.

Camellia sinensis is an evergreen shrub with broad, glossy leaves. The young leaves emerge light green in colour, darkening as they mature. Under cultivation tea plants are usually kept at a height of approximately 1.5-2 metres to make it easy to pick the fresh leaf tips. When picked for tea production only the top 2–5 centimeters of the mature plant are picked. These buds and leaves are known as 'flushes'. A tea plant will typically grow a new flush every seven to 15 days during the growing season in subtropical to tropical climates.

When left to its own devices you can expect a mature tea plant to reach a height of 16 metres. Unfortunately it is only considered to be half hardy and cannot be grown outside in England without winter protection.

HOW TO GROW MANDARIN ORANGE FROM SEED - Citrus reticulata

Mandarin orange plant growing in the snow
How to grow the Mandarin orange from seed



Check out any decent book on citrus plants and you will be surprised at just how many cultivars there are available bearing in mind there are little over 20 species across the entire globe. This is because they can hybridise easily and have been done so in Asia for many thousands of years! In fact according to molecular studies, hybridization between mandarin, citron, pomelo, and the papeda are responsible for most other commercial citrus varieties,

The mandarin orange - Citrus reticulata, is one of those true species and as such will grow true from seed, and luckily enough is relatively easy to germinate. To begin with you will need to obtain fresh viable seed. This can be achieved by collecting your own seed from shop bought fruit or purchase your own from a reputable online seed retailer.

Self-collected fruit will need to be cleaned so that any pulp has been removed and will be ready for immediate planting without any further preparation. Purchased seeds are likely to have dried off a little and as such will need to be soaked for 12-24 hours in tepid water.

How to grow the Mandarin orange from seed

Using modular seed tray or small terracotta pots (approximately 7-9 cm in diameter) filled with a good quality soil-based compost such as John Innes 'Seed and Cutting', sow in seed per pot or module approximately 1 cm deep. Gently water in and move to the warmest, brightest part of the house but without direct sunlight and keeping the soil moist but not waterlogged at all times. Watering can be reduced by placing the trays or pots under a covering plated of Perspex or glass or keep them inside a clear, sealed polythene bag. This will also help to maintain high humidity. Germination times are directly affected by soil temperature and that can be improved by placing the pots or tray inside a heated propagator at a temperature at approximately 18-22 degrees Celsius. You can expect germination to occur from 14 days onwards, however germination will be erratic. That being said, viability of mandarin seeds is high so don't throw un-germinated seeds away until they gave been allowed a month or two to emerge.

Germinated seeds can be removed from the heated seed tray or sealed bag and placed in a cooler position. If used, any germinated plants under the covering plate will also need to be removed

Once the seeds have reached 3-4 inches high they can be potted on in to a larger pot with slightly acidic, richer soil-based compost.

In regions prone to freezing conditions your mandarin plants can be grown as a houseplant or as a container plant outside once they have been acclimatised for a week or so before being left in sunny conditions. Be aware that Mandarins will need to be brought back under protection once overnight temperatures reach 6-7 degrees Celsius. Do not re-acclimatise in the spring until the threat of late frosts have passed.

Keep the compost moist and feed with a liquid soluble citrus fertiliser ever couple of weeks during the growing season.

HOW TO GROW THE CHRISTMAS BOX - Sarcococca hookeriana var. humilis

Sarcococca hookeriana var. humilis shrub
Sarcococca hookeriana var. humilis



Commonly known as the Christmas Box or Himalayan sweet box, Sarcococca hookeriana var. humilis is a popular garden choice for a winter blooming effect. Native to the Himalayas, the original species is a rarely found, erect -growing evergreen shrub and named in honour of Sir Joseph Dalton Hooker (June 1817 – December 1911), Charles Darwin's closest friend and Director of the Royal Botanical Gardens, Kew.

The 'humilis' variety is a dwarf, densely-branched selection which seldom reached 60 cm high. It was first found in Western China and was introduced to British science by Ernest Wilson in 1908. The shiny elliptic leaves are a deep green colour. The flowers are creamy-white with pink anthers and appear over the winter. Once pollinated these are followed by small black berries. While the flowers are not as attractive as spring and summer flowering specimens, this is more than made up for with the heady, honey scented fragrance that accompanies them.

Sarcococca hookeriana var. humilis will perform best in semi-shade to full shade, but it will tolerate full sun if grown in permanently moist soil conditions. It will require a sheltered position in any moderately fertile, moist but well-drained humus-rich, slightly acidic soils althugh it will also thrive in heavy clay and chalk. It is also tolerant of atmospheric pollution, dry shade and (which is good news for most gardeners) neglect. Newly planted specimens will need to be watered regularly until they become established.

They are relatively cold hardy and will grow fine in the warmer regions of the United Kingdom and Ireland. The further north you go you will need to consider apply cold protection.

You can also grow Sarcococca hookeriana var. humilis as a low maintenance container plant using soil based compost such as John Innes No.3.

It is generally, pest free, trouble free and does not require regular pruning. However you can remove any unwanted suckers from the base of the plant. If you do need to prune the do so in the spring after flowering has finished.

HOW TO GROW A COFFEE PLANT FROM SEED

Mature coffee plants in full flower
How to grow a coffee plant from seed

Everyone is familiar with coffee, and you can purchase the beans readily enough when required to ground down and make a steaming cup of coffee. However, be aware that you cannot germinate these beans as they have been roasted prior to package - rendering them effectively lifeless.

The actual bean is of course the seed. When harvested and cultivated correctly will germinate and grow into a new coffee plant capable of producing its own beans. The two most commonly used species for coffee production is Coffea arabica and Coffea canephora. Coffea arabica is indigenous to the forests of the southwestern highlands of Ethiopia, while Coffea canephora has its origins in central and western sub-Saharan Africa

To grow a coffee plant from seed you will first need to purchase fresh, viable coffee seeds. These can usually be found at specialist seed suppliers online or available in good quality garden centers.

Once you have received your coffee seeds they will need to be soaked in tepid, sterilised or distilled water for 24 hours. Cooled, previously boiled water will be fine

Using a modular seed tray filled with damp sand or preferably wet vermiculite in which the excess water has been drained sow the seeds by pressing inseed into the surface of the media, but do not bury. Otherwise, you can place the seeds between moist hessian material, which should be watered twice a day. Drain off the excess water as the roots will not survive waterlogged conditions. Place the coffee seeds in a warm bright position but out of direct sunlight. Using a heated propagator will provide the fastest germination times, use a temperature of between 18-22 degrees Celsius. Germination time will be between 2 and 6 months depending on rooting temperature.

Once the coffee seeds have germinated and are large enough to handle, very carefully remove it from modular tray hessian fabric disturbing the root system as little as possible. Those seedlings grown in vermiculite should lift out with the least damage.

Using 9-10 cm terracotta pots containing a well-drained slightly acidic (ericaceous) loam soil with a high humus content, make a hole about 1.25 cm deep and gently plant the coffee seedling. If you are growing a large number of seedlings then consider adding well-rotted manure, bone meal, and dried blood to the compost mixture. The seeds should be watered daily to keep the roots moist at all times, but again allow any excess water to drain away.

Orchid fertilizer can be used once a month.

The coffee plant has evolved to grow in tropical conditions and so cannot be left to grow outside in mediterranean or temperate climates. Once established, water twice a week, keep the soil moist but well drained. You can expect your speciment to reach flowering age after 2-3 years, which of course are followed by coffee berries.

HOW TO GET RID OF WILD GARLIC

Mature wild garlic plant in white flower
How to get rid of wild garlic

I love wild garlic - Allium ursinum, but as a native to Asia, Europe and the temperate regions of the United Kingdom it has a nasty little habit of self-seeding and taking over your carefully manicured borders. Now a thousand years ago or so this wouldn't have been much of an issue as the bulbs of the wild garlic were a particular favourite of both the wild boar and brown bear (Ursus arctos). Of course, a thousand years ago there wasn't much call for gardening. Alas, both species have since become extinct in Britain (although wild boars are now being reintroduced to the shores), but not due to the efforts of despairing gardeners sick of shooing large mammals from their property.

Now while they may look like a cross between a white bluebell and a lily of the valley, wild garlic is notoriously difficult to eradicate once it takes a foothold. Not only does it self-seed, it produces bulblets from the parent bulb and occasionally the seeds germinate to form growing bulblets (also in leaf) from the pericarp.

Weeding wild garlic

How to get rid of wild garlic
This is the initial response to an outbreak of wild garlic, however in heavy soils the stems tend to break away just below the soil surface. This leaves the bulb in place for the plant to regrow from. In light soils it is possible for the bulb to lift straight from the ground however it is likely to leave any bulblets that may have formed. They best way to lift wild garlic bulbs is to try and loosen the soil below the bulbs using a hand fork or trowel and then lifting the bulb gently with the aid of the hand tool.

There is another issue here as wild garlic is an ephemeral plant meaning that it comes into leaf and flower before deciduous trees leaf in the spring. By the end of June the leaves begin to die back returning energy back to the bulb so if you haven't finished weeding by the end of the spring it may be too late as they would have disappeared to below ground level.

Weed killer

How to get rid of wild garlic
Of course the reason why you are reading this article is because weeding isn't working and so apart from boars and bears your best method of control is likely to be chemical weed killers. That being said you will require a systemic weed killer (such as a glyphosate based product) where the active chemical is drawn into the bulb to kill it off. However wild garlic is surprisingly robust and a single dose will not be enough on mature plants. With systemic weed killer the plant will need to be active growing for the chemical to work efficiently, once overnight temperatures are regularly above 7 degrees Celsius. This means that there is only a short period of time from when the weed killer will work to when the leaves die back so timing will be all important as you will really need at least two applications.

Organic Control

How to get rid of wild garlic
Due to the robustness of wild garlic there is arguably only method of organic control and this is probably best suited for overgrown allotments. This method is to cover the area with old carpet for a year (maybe two, possibly three) and then hand weed any plant resulting from seeds still viable in the soil.

THE GARDENS OF VILLA CASTELLO

Ask anyone with the right passions to name Europe's most important gardens and you can expect to hear the likes of Versailles, the Alhambra and Kew amongst of course many other worthy contenders. However there is one that you have probably never heard of and yet is perhaps the most important of all European offerings. They are the gardens of Villa Castello, located in the hills north-west of Florence, Tuscany. Why is this place so important? Because Villa Castello is the earliest garden  in existence from which you can draw a line of influence directly from its inception during the renaissance through the mannerist, baroque, neoclassical, and romantic periods right up to the present day!

The front entrance of Villa Castello
Villa Castello
Since 1477 Villa Castello was owned by the de' Medici's, an elite banking family whose incredible wealth allowed them to dominate their city's government. With such influence at their fingertips, Villa Castello was 'unofficially' accepted as the seat of power in Florence.

However it was set to change in 1537, when the current resident of Villa Castello, the Duke of Florence, Alessandro de' Medici, was assassinated by a distant cousin creating a massive power-vacuum in the region. The influential men of Florence decided to take advantage of this and replaced Alessandro de' Medici with the little known Cosimo I de' Medici. They believed they could rule the city state with the 17 year old Cosimo I as a puppet figure, enriching themselves in the process at the expense of Florence.

Cosimo I was persuaded to sign a clause which entrusted much of the power to a council comprising of 48 members, but quickly rejected it. During this same period the news of Alessandro de' Medici's death, spurred Florentine exiles (along with the support of France) to invade Tuscany with the objective of deposing Cosimo I. The invasion failed, and all prominent and high profile prisoners were beheaded. In an extremely short period of time and against considerable odds Cosimo I had manage to established himself as the unrivalled ruler of Florence.

Cosimo I de Medici by Jacopo Carucci

Of course Florence was still in turmoil, but with his position as head of the de Medici bank secure Cosimo settled back into Villa Castello and focused his attention on a grand and ambitious plan for the gardens. It may seem strange to undertake a major project during such uncertain and dangerous times but Cosimo had been inspired. The garden was to act as a symbol of his new order, a distinct contrast to the many previous years of Florentine family feuds, political confusion, and poor economic conditions. The renowned sculptor Niccolò Tribolo was commissioned to create the fountains and statues, but more importantly Tribolo was required to design a garden that would become a physical representation of good government as well as reflect Cosimo's sophistication and power. This new garden would prove to visiting rulers and dignitaries that the de' Medici's were the only family that could bring long term prosperity and happiness to Tuscany.

A garden that was deliberately intended as a parade of cultured power was something new in 16th century Italy. Yet while the layout of the gardens exemplified the high renaissance and maximised the views of the surrounding countryside, they are both based upon well-established models of garden design.

It was divided into sixteen compartments, each one reflecting further, perfect geometric shapes which demonstrated the control of man over space and nature. It was also the first time that an axis was used (and still exists to this day) splitting the central path from the Grotto to the Villa using the extraordinary and impressive fountain of Hercules and Antaeus as the centre point. This highly geometrical design created a perspective not seen in any other garden at this time.

Tribolo placed symbolic messages throughout the garden, the clearest being the fountain of Hercules and Antaeus.  In Greek mythology Antaeus was the son of Poseidon and Gaia, and he would challenge all passers-by to wrestling matches with the intention of killing them to collect their skulls. Mythology states that so long as Antaeus remained in contact with the ground he would remain strong and tireless. Of course when it was time for Hercules to fight Antaeus he found that he could not beat him simply by throwing him to the ground as Antaeus had the power to rapidly heal all wounds. However Hercules soon discovered the secret of his power and holding Antaeus aloft he crushed him to death in a bear-hug. This showpiece fountain at Villa Castello is a representation of how Cosimo, like Hercules, defeated his enemies through wisdom rather than just brute strength.

All the fountains at Villa Castello depended upon gravity and water pressure to function, and fortunately the villa was located near a Roman aqueduct. In fact the name Villa Castello is taken from the old water cisterns (known as ‘castella’) near the site. Frustratingly, the Roman aqueduct was in no fit state to supply the villa and so Piero da San Casciano constructed a new system of aqueducts to bring water into a new reservoir built in the sacred bosco.  This is still in place within the elevated section of the garden. The reservoir controlled the water using a system of bronze pipes which, hidden from view,  entered the main body of the garden. While it is true that many of the fountains have been removed, the statue of Appennino which symbolise the mountains of Tuscany,still survives in the reservoir. Here he is portrayed as a shivering old man and when the hydraulics were still functioning would have spent his life under a constant flow of cold mountain.

The figures of Hercules and Antaeus designed by Niccolò Tribolo
 The fountain of Hercules and Antaeus
The reservoir also fed two fountains that were once fitted within the recesses either side of grotto. Each of these fountains represented one of the two rivers of Florence, the Arno and Sieve. These 'rivers' flowed in channels through the garden, while other pipes carried water to the two main fountains. The water pressure was so effective that the fountain of Hercules and Antaeus produced a jet of water which spouted a full three meters from the mouth of Antaeus. The second fountain, 'The fountain of Florence, or Fiorenza' was originally located in the upper part of the garden near to the grotto. However in 1788 the fountain was moved to La Petraia, a villa also owned by the Medici’s where it can still be seen today.

Once the water had passed through the fountains, the overflow was split into and channelled into two small private gardens on either side of the villa. From there the overspill entered two large fish ponds in front of the villa. After that, the water was used to irrigate the fields and gardens below. The area where once the fish ponds existed have long since been filled in and turned over to lawns.

Sadly today most of the formal ponds have also been filled in, and the majority of the original fountains have been dismantled and the water to the grotto switched off. However in its heyday the hydraulic system of this garden was one of the wonders of the High Renaissance. Designed and engineered by Piero da San Casciano they too played an important part in the symbolism of the garden.

Not everything in the garden was to do with expressing power and control, it was also about fun. With the turn of a key the gate to the grotto could be locked, leaving  guests inside to be soaked with water from hidden pipes. In the original design the fountain of Hercules and Antaeus was surrounded by a circle of trees and yet again by a  hidden pipe. Once again, unsuspecting visitors looking at the fountain could be sprayed with water from hidden nozzles.

The Fountain of Appennino, by Bartolomeo Ammannati (1563)
The Fountain of Appennino,
Perhaps the most famous feature of the garden is the ‘grotto of the animals’, an exquisite man-made cave entered by a doorway at the far end of the garden. The walls of the cave are covered with limestone to resemble a natural cavern. The roof is also decorated with stones, mosaic and seashells. In three chambers around the grotto there are set pieces of marble birds and animals housed above a large sculpted marble basin. When the grotto was fully functional, water streamed down from the ceiling and down walls into the marble basins.

The important point to remember is that garden at Villa Costello was one of the first and most influential of a great wave of Italian gardens that were built during the latter half of the sixteenth century. Villa Costello not only stamped its highly distinctive mark on subsequent Medici properties (such as Villa di Pratolino and the Pitti Palace), but it reached out beyond Italy to influence the gardens of the French, and later the English renaissance including the grand gardens of Versailles and Hampton Court.

It hard to believe that the entire citrus collection of approximately 500 plants was almost lost during the Second World War. The building used to over-winter the collection was converted to a hospital leaving no place of the seasonal protection of these tender plants. Left outside, many of the citrus specimens died during the cold, wet winters but all was not lost. Gardeners returning from the war quickly assessed the dire situation and were able to save some of the trees through grafting. You can still see the effects of these traumatic years in citrus plants bearing carefully bandaged scars.

Today, Villa Costello is perhaps the most authentic renaissance garden in existence, and holds one of the world’s largest collections of cultivated citrus grown in terracotta vases. Incredibly, some of these vases date back to 1790 and a few still include the original plants! Although the Villa has been the home of the prestigious Crusca Academy since 1583, this fascinating history along with the plants and gardens can all be yours for free. Why? Because there is no charge for access to the gardens. Get the timing of your visit right and you can also gain access to the secret gardens, but don’t tell anyone you heard it from me. As I said, it’s a secret!
