Planting Asparagus

Because asparagus is a perennial plant, select an area of you garden to which you are willing to devote the next twenty to thirty years to growing asparagus. As a very hardy plant, asparagus can be planted as soon as you can work the soil in your garden, which is from the middle of April to late May in most regions of the United States. To prepare the soil, dig trenches about a foot deep. Spread a layer about six inches deep of phosphorus-rich fertilizer or compost in the bottom of the trench. Space your asparagus crowns approximately every one foot on top of the fertilizer or compost in the trench. Fill in the rest of the trench with loose soil. You should lightly water the transplanted crowns immediately planting; however, asparagus is very tolerant to drought, so supplemental watering throughout the growing season is usually unnecessary and may result in damaged or diseased asparagus plants.

Asparagus can be harvested beginning during the third growing season. However, during the third year, asparagus should only be harvested during the first month; you can harvest through the season after the fourth year.

Do not cut below the surface of the soil because doing so may damage the crown and prevent new spears from growing during the next growing season. At the end of the growing season, remove all remaining spears and cover the plant with fertilizer.
