I played hookey from design work yesterday to take advantage of a brief dry spell. We had ordered 50 crowns of Jersey Giant Asparagus and the bed had to be prepared thoroughly. A well prepared and tended asparagus bed can produce for twenty years, so I want to do it just right.
First I levelled the bed and dug a 4″-5″ deep trench.
Then I spread two types of commercial compost and a natural organic plant food. Using a spading fork, I thoroughly mixed these materials with the soil to a depth of 12″.
I removed much of this amended soil and am left with a trench about 8″ deep with 3-4″ of amended soil at the bottom to place the crowns on. As the spears emerge and grow, the excavated soil will be gradually added to fill the trench.
