Can you overwinter wax begonias?
Below 32 degrees, my wax begonias shrivel up and die.
I am thinking of potting them up and trying to overwinter them in my garage.
Has anyone done this. I also have a loft (unheated) with a sunny window - I may try that.
They are not expensive to buy in the stores, but I want to experiment, but not waste my time if they are hard to do
Thanks so much for any replies
