How to overwinter dahlias
1.Protect your dahlias from frost over winter. After the first frost you can choose to either leave the tubers in the ground or dig them up and store them in a frost-free place.
2. You can leave them in the ground if you live in a mild region or have light, free-draining soil. It is a risk as repeated hard frosts can lead to some losses. Cut down the stems and cover with mulch or homemade compost.
