Methods of Asparagus Propagation
1. Division
Dividing established asparagus crowns is the most common and effective method of propagation.
- Steps:
- Dig up the asparagus crown in the fall or spring.
- Use a sharp knife to divide the crown into smaller sections, each with at least one bud.
- Replant the divisions in prepared soil, spacing them 12-18 inches apart.
2. Seed
Growing asparagus from seed is a more time-consuming method but can be rewarding.
- Steps:
- Sow asparagus seeds in the spring in well-drained soil.
- Thin the seedlings to 6-8 inches apart.
- Transplant the seedlings to their permanent location after one year.
3. Root Cuttings
Root cuttings are a less common but viable method of asparagus propagation.
- Steps:
- Dig up asparagus roots in the fall or spring.
- Cut the roots into 3-4 inch sections.
- Plant the root cuttings vertically in well-drained soil, leaving the top 1-2 inches exposed.
Site Preparation and Planting
For successful asparagus propagation, follow these guidelines:
- Site: Choose a sunny location with well-drained soil rich in organic matter.
- Soil pH: Asparagus prefers a soil pH between 6.5 and 7.0.
- Planting: Plant asparagus crowns or seedlings 6-12 inches deep and 12-18 inches apart.
Care and Maintenance
After planting, provide proper care to ensure healthy asparagus growth:
- Watering: Water regularly, especially during hot and dry weather.
- Fertilizing: Fertilize asparagus annually with a balanced fertilizer.
- Mulching: Spread a layer of organic mulch around the asparagus plants to suppress weeds and retain moisture.
Harvesting and Regrowth
Harvesting
- Timing: Harvest asparagus spears when they are 6-8 inches long, typically in the spring.
- Method: Use a sharp knife to cut the spears at ground level.
Regrowth
- Cutting Back: After harvesting, cut back the asparagus foliage to the ground.
- Fertilizing: Fertilize the asparagus bed to encourage new growth.
