Answer: The best strategy for building a successful asparagus bed is to dig 12" wide planting trenches 6"-8" deep and 4' apart. Set the crowns with their roots draped over small mounds of soil or compost 1 1/2 to 2' apart in the trenches; top with 2" of soil. In two weeks, add another 2" of soil. Continue adding soil every two weeks until the soil is slightly mounded above surface level to allow for settling.
