Shredded paper works to reduce evaporation and drying out of tubers. Cardboard boxes or paper bags can be used, and peat moss, coarse sand, sawdust, wood shavings or vermiculite work instead of shredded paper. There’s a balance on keeping the tubers dry without drying them out.
At what temperature can you store dahlia tubers?
A: Bring your dahlias inside once they’ve been touched by frost and start to wilt. Cut the tops off and dig to retain as much soil around the roots as possible. These encased roots can then be stored in boxes in a basement at 7 to 13 degrees Celsius.
What temperature should dahlia tubers be stored at?
The ideal storage temperature is above freezing but below 50 degrees Fahrenheit. Be sure to check the tubers a couple times over the winter, and discard any that have rotted.

Can you grow dahlias in pots indoors?
If started inside, place the containers under plant lights. The dahlias should have light from above to keep them from bending towards the light of a window and to grow compactly. Set the lights about six inches from the tops of the pots of newly planted tubers. Raise the lights as the plants grow.
Do dahlias like deep pots?
Don’t fill the pot to the top, as the extra soil can hold water that will cause the tuber to rot. As the plant begins to sprout, continue to fill the pot with soil gently around the stalk. This allows the plant to establish deep roots and anchor into the soil.
