Hmm, I didn't realize this was a Canadian forum -- still, it might not matter.

It is also a slow forum at times. I don't overwinter geraniums to be able to help you but there are lots of people that do so.

I imagine your geraniums died last year because they dried out. Even when dormant plants still need water. Unless they were tuberous then other methods should have been taken.

If you google "overwinter geranium" lots comes up.

Good luck

I pot them into small peat pots and keep them over winter.
But I also would cut them back and make cuttings.
They do need a bit of water------and more later when you want to get them growing again.

( my one bathroom is full of geraniums which I brought in before the cold hit.)

Mine are mostly in containers. I bring them all in for the winter and they sit in a sunny west window with minimal water all winter. In the spring, I start watering again. Some I'll take cuttings from, others just prune back and put them outside again. I've kept them for years that way.
