Digging up dahlia tubers is essential in preserving the plants for future growing seasons, particularly in areas with colder climates. THis video demonstrates that process.
- Timing: Wait until after the first frost has blackened the foliage, signaling that the dahlias are ready to be dug up. Depending on your region, this typically happens in October.
- Preparation: Cut the foliage to about 4-6 inches above the soil level. This makes handling easier and reduces the risk of damaging the tubers.
- Digging: Carefully pull the top layer of soil away from the base of the plant. In this video I use a small spade to dig under, leaving ample space to avoid damaging the tubers. Carefully lift the tuber cluster out of the soil being carefull not to break any.
- Cleaning: Shake off excess soil and gently wash the tubers with water. Allow them to air dry for a day or two in a cool area out of direct sunlight.
- Dividing Tubers: You can divide the tubers at this stage if desired. Look for "eyes" (small bumps) on the tubers, which indicate growth points for next season. Each divided section should have at least one eye.
- Storing: Store the cleaned and dried tubers in a cool, dark, and dry place (around 40-50°F). Place them in peat moss, wood shavings, or paper bags to prevent moisture buildup and rot. Check periodically through winter for any signs of rot or drying.
Following these steps will help ensure that your dahlia tubers are protected through the winter and ready to be replanted for another season of blooms next spring.
