Soil Preparation and Planting
Asparagus prefers well-drained soil with a pH between 6.5 and 7.0. Before planting, amend the soil with compost or manure to improve fertility and drainage. Dig trenches 12-18 inches deep and 18-24 inches apart. Place the asparagus crowns in the trenches, spacing them 12-18 inches apart. Cover the crowns with soil and firm it gently.
Fertilizing and Watering
During the first year of growth, fertilize asparagus monthly with a balanced fertilizer. In subsequent years, fertilize in early spring and after harvesting. Water asparagus deeply and regularly, especially during hot, dry weather. Mulching around the plants helps retain moisture and suppress weeds.
Harvesting and Storage
Asparagus spears are ready to harvest when they reach 6-8 inches in length. Cut the spears at ground level using a sharp knife. Harvest asparagus daily or every other day during the season, which typically lasts from late April to early June. Store asparagus in the refrigerator for up to a week.
Pest and Disease Management
Asparagus beetles and rust are common pests and diseases that can affect asparagus plants. Control beetles by handpicking or using insecticidal soap. Prevent rust by practicing good sanitation and using disease-resistant varieties.
Companion Planting
Companion planting can benefit asparagus growth. Plant asparagus alongside tomatoes, carrots, onions, and marigolds. These companion plants help deter pests and improve soil health.
Succession Planting
To extend the harvest season, consider planting asparagus in succession. Plant a new bed of asparagus every 2-3 years. This will ensure a continuous supply of fresh asparagus for several months.
