Growing Dahlias: The Basics
Dahlias are surprisingly easy to grow with the right conditions:
1. Planting
-
When: After the last frost date in your region, usually late spring.
-
Where: Full sun (at least 6-8 hours a day).
-
How: Plant tubers 4–6 inches deep, spaced 18–24 inches apart.
2. Soil
-
Well-draining, fertile soil is essential. Mix in compost or aged manure before planting.
3. Watering
-
Water deeply 2–3 times a week once established. Avoid overwatering early on, as tubers can rot.
4. Staking
-
Taller varieties benefit from staking early to prevent wind damage.
5. Deadheading
-
Regular removal of spent blooms encourages more flowers and keeps plants tidy.
6. Winter Care
-
In colder zones (below USDA Zone 8), dig up and store tubers in a cool, dry place for the winter.
