Plant seed in spring, about one inch deep, spaced two to three inches apart, within rows that are a foot apart. Seeds can take three weeks to germinate. Keep the nursery bed free from weeds, as the asparagus seedlings will not be able to compete with strong weed growth.
How deep does the soil need to be for asparagus?
To plant asparagus crowns, dig trenches 12 inches wide and 6 inches deep (8 inches in sandy soil) down the center of the prepared bed. Soak the crowns in compost tea for 20 minutes before planting. Place the crowns in the trenches 1½ to 2 feet apart; top them with 2 to 3 inches of soil.
How do you plant bare root asparagus?
Bare Root Asparagus Amend the soil with a planting mix like Soil Booster. Dig a trench 8-10” deep. Place asparagus crowns 12” apart spreading roots over the mound. Cover crowns with 2” of soil. As tips emerge fill soil around them. It takes asparagus 2-3 years to reach maturity.

How deep should asparagus bed be?
Asparagus crowns are usually available just once a year in early spring. So plan accordingly. Once the bed is weed-free, dig a trench about 12″ deep and a foot wide.
