To plant asparagus successfully, focus on proper spacing, depth, and ongoing care. Here's a step-by-step guide:
1. Site Selection & Soil Preparation:
- Choose a sunny location: Asparagus needs at least 6-8 hours of sunlight per day.
- Prepare the soil: Asparagus prefers well-drained soil with a pH of 6.5-7.5. Amend the soil with compost or well-rotted manure to improve drainage and fertility. Remove any rocks or debris.
2. Planting Asparagus Crowns:
- Timing: Plant asparagus crowns in early spring, typically after the last frost.
- Spacing: Space plants 18 inches apart in rows that are 5 feet apart.
- Digging Trenches or Holes: Dig trenches or individual holes that are approximately 8 inches deep and 10 inches wide.
- Planting the Crowns:
- Create a small mound of soil in the bottom of the trench or hole.
- Place the asparagus crown on top of the mound, spreading the roots out around it.
- Cover the crown with about 2 inches of soil.
- Water Thoroughly: Water the newly planted crowns gently but thoroughly.
3. First Year Care:
- Gradual Filling: As the young asparagus shoots grow during the first summer, gradually fill in the trench or hole with soil. This encourages strong root development.
- Weed Control: Keep the area around the asparagus plants free of weeds, which compete for nutrients and water.
- Watering: Water regularly, especially during dry periods.
- Fertilizing: Fertilize lightly with a balanced fertilizer (e.g., 10-10-10) according to package instructions.
4. Patience is Key:
- Do not harvest asparagus during the first year. This allows the plants to establish a strong root system.
- Harvest sparingly in the second year, picking only the thickest spears for a short period (2-3 weeks).
- Full Harvest in the Third Year and Beyond: By the third year, you can harvest asparagus spears for a longer period (6-8 weeks).
5. Ongoing Maintenance:
- Fertilize annually: Apply a balanced fertilizer in early spring.
- Mulch: Apply a layer of mulch around the plants to suppress weeds, retain moisture, and moderate soil temperature.
- Cut back foliage in fall: After the ferns turn yellow or brown in the fall, cut them back to ground level.
By following these steps, you can successfully plant and grow asparagus for years to come!
