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.
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.
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.
