Planting and Care

Plant dahlia tubers in spring. Dahlias are frost-sensitive, so protect the tubers from late frost. For successful planting:

2. Fill the hole with good-quality potting soil.

3. Place the tubers carefully and cover with 3–5 cm of soil.

4. Maintain a spacing of 30–60 cm between plants.

Dahlias thrive in full sun. After flowering, store the tubers in a frost-free location to enjoy them for years.

• Deadhead regularly to encourage continuous blooming.
