Asparagus is a perennial bulb and stem vegetable that pops up through the ground every spring. It may take up to 2 to 3 years to get started and productive, but once established the plant can be productive for many years.
To plant: Dig trenches of about 6 inches wide and 6 to 12 inches deep. Asparagus does not like to have its feet “wet”, so be sure your bed has good drainage. Create a mound in the trench and plant the crowns 15 to 18 inches apart, spreading the roots over the ridge. Cover the roots and crowns with soil 2 inches deep and water thoroughly. As the stems grow,fill in the rest of the trench with soil, leaving 3 to 4 inches of the stem exposed.
Harvest: you will have to wait until year three to harvest any asparagus. Harvest for 2-3 weeks. After you harvest, leave the ferns so it can gather nourishment for next year’s growth.
