GROWING ASPARAGUS FROM SEED
Although considered by many as a gourmet vegetable, the asparagus is often over looked as a 'run-of-the-mill' garden crop. This is a real shame as shop bought, imported varieties really don’t have the same sublime flavour as quality home-grown produce.
When buying asparagus plants for a newly created asparagus bed, most plant retailers will only offer a small range of one or two year old plants. Although they will always look healthy in the pots, there is always a risk of failure when it comes to transplanting - around 10%-15% for one year old stock and as high as 20% for 2 year old stock. When paying full retail prices - particularly with regards to 2 year old stock - this can end up being an expensive lesson.
Growing asparagus from seed - either in pots or directly into the beds - gives the best viability, with a survival rate of around 100%. In addition, with direct sowing there is no transplanting or root shock to delay valuable root development.
The best time to sow asparagus seeds is around mid-April when the ground is warm enough to initiate germination. A good tip is to soak the seeds in water for a couple of hours before planting. You will find that this will help to speed up the germination process considerably.
Once the bed has been prepared raked over the top layer into a fine tilth, then sow the seed into thin rows down to a depth of about 2 inches. Depending on how many plants you intend cropping each subsequent row should be between 12 and 18 inches apart. Water them in well if conditions are dry.
The new seedlings should emerge in about 3 weeks, and as soon as they are large enough they can be thinned out to about 2in apart.
Then, once the seedlings reach about 6 inches high, they can be thinned out again to around 18 inches apart. For the rest of the year you just need to keep the beds weeded and the plants well-watered.
If you have bought seed varieties that produce both male and female plants, you will need to remove any female forms as soon as they become identifiable - normally from their berries.
Some asparagus varieties like the popular 'Connovers Colossal' are best sown indoors and this can be done any time between February and March. Again, try soaking them for a couple of hours, then plant them into individual pots containing moist John Innes seed compost. Place them in a warm room at approximately 15-18 degrees Celsius then, once germinated, move to to a cool, light area such as a windowsill, but keep them out of direct sunlight. Once the threat of frosts are over they will need to be gradually accustomed to conditions outside - this known as 'hardening off' and can take between 2-3 weeks. Once they are ready to be moved out into the asparagus bed proper, they can to be planted fairly deeply leaving a couple of inches of soil above the level of the compost. Keep them nicely watered over the summer period and - as always - keep the bed free of weeds, especially perennial weeds which will compete with your seedlings roots for nutrients.
Growing your own plants can delay establishment of your bed by an additional year, but it does ensure that you are starting with new crowns that have not lost none of their vigour through being lifted, stored and shipped. However, not only will you have a larger selection of varieties available to you, if you choose your varieties wisely you will still be able to harvest in their second year.
