Dahlia Plants

Dahlia Plants

Dahlias are some of the most rewarding plants you can grow. They are perfect for filling your flower garden with colour from late July right through to the first frosts. These flower plants produce long-lasting flowers that come in a huge variety of shapes, from delicate pompons to bold dinner-plate flowers, meaning they can fit any planting style.

Our 3-litre dahlia plants arrive in 18cm (7in) pots with strong, well-developed root systems, ready to be planted straight into borders or containers. The foliage height varies between varieties, but every Dahlia plant is grown to establish quickly and produce months of non-stop flowers. Just plant them, keep them watered, and enjoy their stunning flowers right up until the end of November.

When to Plant Dahlia Plants

Dahlia plants should be planted after the risk of frost has passed, usually from late May to early June. They thrive in warm, well-drained soil and need plenty of sunlight. If planting in containers, choose a large pot with good drainage to support healthy growth.

How to Grow Dahlia Plants

Plant dahlias in a sunny spot with fertile, well-drained soil. Space them according to their expected height and spread, generally around 45cm (18in) apart. Water regularly, especially during dry spells, and deadhead spent flowers to encourage continuous blooming. Taller varieties may need staking for support.
