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.
