Growing Dahlias: Planting and Care
Successfully growing dahlias requires attention to planting and care techniques.
Choosing the Right Location
Select a sunny location with well-draining soil for optimal growth. Dahlias thrive in full sunlight and need protection from strong winds.
Soil Preparation
Prepare the soil by incorporating organic matter like compost to improve fertility and drainage. Ensure the soil pH is slightly acidic to neutral (6.5-7.0) for best results.
Planting Process
Plant dahlia tubers in spring after the danger of frost has passed. Dig a hole, place the tuber with the eye facing upwards, and cover with soil.
Watering and Fertilizing
Keep dahlias consistently moist but not waterlogged. Fertilize regularly during the growing season with a balanced fertilizer to promote healthy growth and abundant blooms.
Managing Pests and Diseases
Watch out for common pests like aphids and spider mites. Prevent fungal diseases by providing good air circulation and avoiding overhead watering.
Seasonal Care and Maintenance
In colder climates, dig up dahlia tubers in autumn and store them indoors until the next planting season. Prune dead foliage and inspect tubers for signs of rot or damage.

Dahlias make stunning additions to gardens, adding color and texture. They pair well with other late-season bloomers like asters, ornamental grasses, and salvias.
