How to Dig, Divide & Store Dahlia Tubers
Dahlias are a favorite in the garden, blooming with vibrant colors through late summer and fall. To keep them thriving for years, it’s essential to dig up, divide, and store their tubers correctly once the growing season ends. Follow these steps to ensure your dahlias survive winter and are ready to replant next season!
Steps:
- Wait for the First Frost: Let the first frost hit, which will cause the plant tops to die back—signaling it’s time to dig up the tubers.
- Dig Up the Tubers: Use a garden fork to carefully dig around the base of the plant, lifting the clump without damaging the tubers.
- Clean the Tubers: Shake off excess soil and rinse the tubers gently with water to remove any remaining dirt. Allow them to dry for a day.
- Divide the Clumps: Use a sharp, sterilized knife to divide the tubers. Ensure each division has at least one “eye” (the small buds where new growth starts).
- Cure the Tubers: Place the tubers in a dry, cool place for 1-2 weeks to allow the skin to harden, which helps prevent rot during storage.
- Store the Tubers: Pack the cured tubers in a box filled with peat moss, vermiculite, or wood shavings, then store them in a cool, dark location (like a basement or garage) at 40-50°F.
- Check Periodically: Inspect the tubers monthly for any signs of rot or shriveling. Lightly mist if they appear dry.
