Dahlias Survive Winter

OUTSIDE

Although it is a little early for me as far as dahlias are concerned, I wanted to see how they had coped with the winter.
As you can see from the photo, I was lucky enough to have added some dry peat, just before the harshest frosts, to the tops of the dahlias overwintered in the front border. Then we got 30 centimeters (one foot) of snow which seems to have kept them a bit warmer.

I dug one up to have a look at the tuber. It seemed fine. Left it at that. Did not want to disturb them unnecessarily.


INSIDE
Removed covering of newspapers from dahlias stored in unheated garage. Seem to have survived O.K. They seem to like some drying soil around the roots. And treating them with Derris Dust seems to have controlled centipedes.
