The arrival of spring brings the excitement of planting dahlias, and if you’ve found your tubers have already sprouted, don’t fret! With proper care, you can still enjoy these vibrant blooms in your garden. Here’s a comprehensive guide to planting dahlia tubers that have sprouted:
1. Preparation
Materials:
- Sprouting dahlia tubers
- Potting mix
- Pots or containers
- Water
- Liquid fertilizer
Steps:
- Check for Roots: Gently remove the tubers from storage and inspect them for roots. If you notice any roots, proceed to the next step.
- Trim Sprouts: If the sprouts are more than 2 inches long, carefully trim them back to 1-2 inches. This will encourage bushier growth.
- Prepare Pots: Fill pots or containers with a well-draining potting mix. Ensure the pots have drainage holes to prevent waterlogging.
2. Planting
Steps:
- Plant Tubers: Place the tubers in the pots, with the sprouts facing upwards. Cover them with about 2-3 inches of potting mix.
- Water: Water the tubers thoroughly and allow the excess water to drain.
- Fertilize: Dilute liquid fertilizer according to the instructions and apply it to the soil around the tubers.
3. Placement
Light: Dahlias thrive in full sun, receiving at least 6 hours of direct sunlight per day.
Temperature: Ideal temperatures for dahlia growth range from 55-75°F (13-24°C).
Spacing: Plant tubers 12-18 inches apart to allow for proper growth and air circulation.
4. Growth and Care
Watering: Water dahlias regularly, especially during hot and dry weather. Avoid overwatering, as it can lead to root rot.
Fertilizing: Fertilize dahlias every 2-3 weeks with a balanced fertilizer.
Staking: As dahlias grow taller, stake them to prevent them from falling over.
Deadheading: Remove spent blooms to encourage continuous flowering.
5. Overwintering
Steps:
- Dig Up Tubers: After the first frost, dig up the dahlias and shake off the soil.
- Cut Back Foliage: Cut back the foliage to a few inches above the tubers.
- Dry and Store: Dry the tubers in a cool, dark place for a few weeks. Store them in a frost-free location with good ventilation.
6. Troubleshooting
Problem: Sprouts are weak or spindly.
Solution: Provide more sunlight and ensure the tubers are getting enough nutrients.
Problem: Leaves are turning yellow.
Solution: Check for overwatering or nutrient deficiency. Adjust watering schedule and fertilize accordingly.
Problem: Tubers are rotting.
