Dahlias are a must have for the summer border or patio display. They can flower until Autumn and have a wide range of interesting varieties, all with very showy flower shapes and rich colour shades.
Gallery Dahlias are a more compact, bushy dwarf variety which are ideal for borders as they will flower beautifully well into Autumn. They are also perfect for tubs and pots.
How to grow
- Grow in fertile, humus-rich, well-drained soil, enriched with organic matter and general purpose fertiliser, in full sun.

- Water freely in dry periods.

Aphids, leaf miners, glasshouse red spider mite and slugs are common pests. Earwigs sometimes damage blooms. Capsid bug and caterpillars are occasional pests
Powdery mildews can be damaging in dry conditions. In wet weather grey moulds and other fungal rots can be a problem. Fungal rots can also damage stored tubers. A virus may cause stunting, leaf markings and distortion
Propagate by softwood cuttings taken in spring from shoots from stored tubers, or divide the tubers ensuring each division has a viable bud
