The success achieved when growing asparagus is in direct proportion to the care taken in preparing the soil.
Asparagus matures very slowly.
It takes three years from seed to first light harvest.
Planting seed in the garden is taking the longest possible route to fresh homegrown asparagus.
Most gardeners begin planting the crops in May.
Cut a full year off the maturation time by planting one year old roots.
Two year old roots are also available but many gardeners prefer the younger ones.
When the two year old roots are dug from the nursery bed, so much of their structure is left behind that they are slow to recover from the shock of relocation.
When building an asparagus bed, keep in mind that growing asparagus roots need a thick layer of soil protection from the elements and the hazards of cultivation.
How to plant asparagus:
Step 1. Dig a trench a foot deep and 18 inches wide.
Leave a distance of 4 feet, center to center, between the trenches, if planting more than one row of asparagus.
Step 2. At the base of the trench, break up the soil to the depth of a spading fork, around 8-10 inches.
Step 3. Add ½ pound of 10-10-10 fertilizer to each 10 foot stretch of trench in your asparagus bed.
Asparagus thrives in neutral soil, with a pH of about 7.0.
If a soil test shows the trench soil in your asparagus bed is too acid, sweeten it with ground limestone.
Step 4. Then add 4 inches of aged compost in the bottom of the asparagus trench, which will keep the plants well fed for years.
Step 5. To give the roots a solid base to rest on, walk over the soil in the bottom of the trench to firm it.
Step 6. Then rake it to make it level.
Step 7. Fan the asparagus roots out like the arms of an octopus.
Step 8. Lay them at 2 foot spacing along the floor of the trench.
Step 9. Cover the fragile roots gently with 2 inches of garden soil.
As the summer progresses, pull in more soil from the sides of the trenches until the asparagus bed is filled in completely.
Every three months or so, dress the rows of growing asparagus with a handful of 10-10-10 fertilizer for each plant.
