That bed is on the hillside beside the garden area. I want to make it as level as possible across the slope. I used stakes and line level because I do not trust my eye.
I dug an 8 to 10 inch trench and made in 12 inches wide.
Then I placed some partially decomposed manure and straw in the bottom of the trench(not quite broken down far enough to be considered compost). A spade fork worked the bottom of the trench loose and combined the organic matter with the subsoil.
The roots will enjoy a pile of compost, fertilizer and greensand, for each asparagus crown placed every eighteen inches.
The trench was back filled with about 3 inches of soil and as the first shoots grow I will cover them with another 3 inches of soil and compost.
That is one sixty foot row. Now I just need to do 3 more rows for this year.
