7. Protect from Pests and Diseases
Asparagus is relatively pest and disease-resistant, but vigilance is still necessary. Monitor your plants for common pests like asparagus beetles and aphids, removing them by hand or using organic insecticides if necessary. Implement crop rotation and avoid planting other susceptible plants nearby to reduce the risk of disease.
8. Practice Patience in the First Year
Patience is key during the first year of growing asparagus. Refrain from harvesting spears in the first year, allowing the plants to establish a strong root system. In the second year, limit harvesting to a few weeks, gradually increasing the harvest period as the plants mature. This patience will pay off with more abundant harvests in the years to come.
9. Harvest Asparagus Properly
Harvest asparagus spears when they reach 6-8 inches in height and are still firm. Use a sharp knife or scissors to cut the spears at ground level, being careful not to damage emerging spears. Regular harvesting encourages continued spear production, so check your bed frequently during the harvest season.
10. Maintain Your Bed Year-Round
Year-round maintenance is essential for a healthy asparagus bed. After the harvest season, allow the ferns to grow and develop, as they help replenish the energy stored in the roots. Cut back the ferns to ground level in late fall or early winter to reduce the risk of pests and diseases. Keep the bed free of debris and weeds throughout the year.
11. Divide and Conquer for Continuous Harvests
As your asparagus bed matures, consider dividing the crowns every 8-10 years to rejuvenate the bed and enhance productivity. Carefully dig up the crowns in early spring, splitting them into smaller sections and replanting them in freshly prepared soil. This process helps maintain plant vigor and ensures a continuous supply of asparagus for years to come.
