Dahlias cannot survive our winters here in North Carolina,
so they must be stored inside over the winter.
There is a process to doing this. I call the steps of the process the “Dahlia Four D’s.”
The first D is to let them die. Okay not really, but they must be killed back by frost to know to go dormant.
The second D is for dig. I chop off the dead stems to about three inches height. Then I dig around then down. That way I do not chop the tubers with my shovel.
The third D is for dry. They need to spend a few days drying before the soil is removed.
The forth D is for divide. Once the tubers have dried a bit, they shrink a little. This makes it easier to untangle the separate stems.
Store these in peat and/or vermiculite. I use boxes that I can stack on shelves.
Leave room for air. I shake these boxes periodically and open them every few weeks to make sure none are rotting or shriveling.
So if you have dahlias, it’s time for the four D’s.
Die, dig, dry and divide.
