How to plant Dahlias

Planting in the Garden

• If panting in the garden, plant in late spring once the risk of frost has passed.
• Find a good location with plenty of sun and drainage.
• Cover your tubers with 3cm (1-2") of soil.
• Allow approx. 30cm spacing between each tuber. (The spacing may vary depending on the final size of the variety.)
• Douse the hole with a watering can full of water and cane as you plant.
• Mulch over to protect them from the risk of any frost.

Planting in Pots/Containers

• If planting in pots, start them off indoors until the risk of frost has passed.
• Keep them indoors in a frost-free location like a greenhouse before transferring them outside after the last frosts.
• Plant 1 x tuber in a 2-3litre pot or 12" in diameter.
• Cover your tubers with 3cm (1-2") of soil.
• Use a good-quality, multipurpose compost.

Aftercare/Overwintering

• Once your dahlias have finished flowering and the first frosts have blackened the foliage, cut the plants back to the ground.
• In well-drained soils, leave the tubers in the ground and mulch over to protect against frosts.
• In colder climates or heavier soils, lift and store your tubers over winter.
• If lifting and storing over winter, cut back foliage and carefully lift the tubers out of the soil. Allow the tubers to dry off naturally and then clean away any soil. Trim the stems back and cut off any fine roots. Make sure the tubers are completely dry before storing them into open trays or boxes. Pack with dry sand. Leave the crowns exposed.
• Replant the following spring.
• Must be kept frost free.
• Once the risk of frosts have passed and you start to see signs of growth again, the mulch can be removed.
• Water regularly during active growth periods.
• See 'Care Instructions' for more information.

 

How to care for Dahlias

Care:

• Support Dahlias with canes on planting and tie in as growth develops.
• When your Dahlias reach about 40cm in height, pinch out the growing tips with your thumb and forefinger or use a sharp knife. This will encourage branching.
• Water once a week with a good amount not just a little sprinkle.
• Deadhead flowers as they fade.

Overwintering:

• Once the first frosts have blackened the foliage, cut the plants back to the ground.
• If panted in the garden, in well-drained soils, leave the tubers in the ground and cover with a generous layer of bark chips or compost to protect them from frost.
• In colder climates or heavier soils, lift and store your tubers over winter.
• If planted in pots, cut back the entire plant to 4 – 6 inches. Keep the dahlias in their pot over winter. Keep the pot in a cool, dry, dark place that doesn't freeze like, garage, shed or greenhouse.
• Don't water your tubers, just let them stay dry.  

Lifting and Storing over winter:

• Cut back foliage and carefully lift the tubers out of the soil.
• Allow the tubers to dry off naturally and then clean away any soil. 
• Trim the stems back to 15-20cm and cut off any fine roots.
• Make sure the tubers are completely dry before storing them into open trays or boxes. Pack with peat-free compost or dry sand. Leave the crowns exposed. 
• Replant the following spring.
