I planted a row of DW begonias in my window box in full sun. They are doing really well. I'd like to see if there is a way that I could overwinter them. If so, how? Thank you for any suggestions and advice.
You could always take cuttings, they root quickly in water.
I have a couple really large pots and the wind blew them over and broke off some stems so I just stuck them in a jar of water and when roots were showing I potted them up.
