Dahlia Tuber 'Le Castel'

How to Grow Dahlias:

Plant dahlias in a sunny spot with well-drained, fertile soil enriched with compost or organic matter. Space plants 30-60cm apart depending on their final size, ensuring good air circulation. Tubers should be planted 10-15cm deep with the crown upwards, while plug plants and potted dahlias can be planted at the same depth as in their pots. Water thoroughly after planting and keep the soil consistently moist but not waterlogged.

Pinch out the growing tips when plants are 30cm tall to encourage bushier growth and more flowers. Stake taller varieties early to prevent wind damage. Regular deadheading promotes continuous blooms, and feeding every 2-3 weeks with a high-potash fertiliser enhances flowering. Lift tubers after the first frost, dry them, and store in a cool, frost-free place for winter, or mulch deeply in mild climates to overwinter in the ground.

Dahlia Plant Sizes:

Dahlias are available in a range of sizes to suit every gardener:

• Tubers: Dormant and ready to plant in spring, producing full-sized plants by summer.
• Garden-Ready Plug Plants: Young plants ideal for direct planting once frosts have passed, growing quickly into healthy specimens.
• 9cm Potted Plants: Well-rooted and easy to transplant, providing a head start on the growing season.
• 2L Potted Plants: Established plants that deliver an instant impact in borders or pots.

All sizes offer vibrant blooms for summer displays, with varieties suited to pots, borders, or cutting gardens.
