After eating an avocado, it is hard to resist planting its seed. However, to get the seed sprouting quickly you need to be quick as the seed will need immediate planting. Luckily there is a tried and tested method when it comes to growing avocados from seed. This is done by poking three toothpicks into the side of the seed so that it can perch, halfway immersed in water, on the rim of a drinking glass. The seed could also be avocado planted in potting soil, but this misses some of the fun of watching the roots and the shoots grow.

Avocado roots, like those of most other plants, need oxygen to grow, so the seedlings would actually grow better in soil than in water. When growing a seedling in water, the water should be changed at least every couple of days to prevent it from getting dirty and depleted of oxygen. One way to speed germination in soil is to remove the parchment like seed coat and slice a thin layer from both the top and the bottom of the seed before planting. In water or in soil, set the seed with its base (the wider portion) down.

Indoors, avocado plants are often gangly and sparse with leaves. One reason for the plant's gawky appearance indoors is lack of light. Lack of sufficient light causes stems to stretch for it, a phenomenon know as etiolation. Another reason is that avocados shed many buds along their stems, buds that might have grown into side branches. The result is a plant stretching out for light, sending out new growth mostly from the tips of the branches and shedding old leaves.

There are several things indoor gardeners can do to keep their plants more attractive. Most obvious is to give your avocado tree brighter, stronger light. Also, the stretch for light is exaggerated when warmth stimulates growth, so the ideal spot for the plant is at the brightest window in the coolest room. Beyond that, pruning back a stem or pinching out its growing tip stimulates branching by awaking dormant buds (not all are shed) further down the stem. There is nothing that can be done about the shedding of older leaves.

Every indoor avocado grower holds out hope for fruit from his or her plant. This is always a possibility, but realistically it is not likely to happen. The time from seed to fruiting under good growing conditions is about a decade. Indoors, this time period is lengthened and plants may never experience good enough conditions to ever flower, let alone ripen fruit.

Lack of fruit on an indoor tree is no great loss, because seedling trees rarely produce fruits as tasty as those on commercial trees, which are grafted to good-tasting cultivars. Indoors, avocados are best looked upon as a house plant that is inexpensive, fun to grow and somewhat attractive.

Growing Avocados outside

The avocado is a tree native to Central Mexico, and are cultivated in tropical and Mediterranean climates throughout the world.

If you want to produce a viable crop from your own avocado tree then you are going to need to have it growing outside. More importantly, it needs to be outside in a climate without frost and with little wind.

High winds reduce the humidity, dehydrate the flowers, and affect pollination. When even a mild frost occurs, premature fruit drop may occur, although the Hass cultivar can tolerate temperatures down to −1°C.

The trees will need well-aerated soils, ideally more than 1 metre deep. be aware that crop yield is reduced when the irrigation water is highly saline.

These specific soil and climate requirements are available only in a few areas of the world. So if you live in one of the following countries then you are in luck.

The countries are southern Spain, Portugal, Morocco, Crete, the Levant, South Africa, Colombia, Peru, parts of central and northern Chile, Vietnam, Indonesia, parts of southern India, Sri Lanka, Australia, New Zealand, the Philippines, Malaysia, Central America, the Caribbean, Mexico, California, Arizona, Puerto Rico, New Mexico, Texas, Florida, Hawaii, Ecuador and Rwanda. Be aware that each region has different cultivars which have been selected over time to fit the prevailing conditions.
