An increasing number of home gardeners in zones 3 to 8 are growing asparagus, a strong and long-lasting vegetable. While it takes about three years before the first harvest, it can produce shoots every year for up to 20 years. Experts suggest planting asparagus crowns—dormant roots sold at garden centers—instead of seeds, as this speeds up the first harvest by a year. Before planting, a sunny location with rich, well-draining soil should be selected, and the soil should be mixed with compost or aged manure to support healthy growth.

The recommended method involves planting crowns in early spring by digging trenches 12 to 18 inches wide and 6 to 12 inches deep, with 3 feet between trenches. Each crown should be placed 12 to 18 inches apart and lightly covered with soil. As spears emerge, soil must be added gradually until the trench is filled. Regular watering is necessary during dry periods, though overwatering must be avoided. Harvesting is advised in the third year when spears reach 6 to 10 inches. Stalks should be cut just below the soil using a sharp knife. After six weeks, harvesting must stop to allow the plant to recover. Remaining stalks grow into fronds, which store energy for the next season and should be trimmed only after turning brown. Crops such as onions and garlic should be planted at a distance, as they may inhibit asparagus growth.
