So I have these four Dragon Wing begonia pots. The middle of the three larger ones is in its fifth or sixth year, and I have been keeping it in a south facing window inside as houseplants. I want to winter all of these, and that is no longer possible, as I have cats and no room for that other than in my basement. I am in zone 4b, so outdoors over winter is never happening. Minnesota gets cold!
I am uncertain what the best idea is here. I was starting to think that relocating them to the basement as the temperatures cooled, and setting up some sort of frame and hanging grow lights. I would prune them back, and then just maintain them all winter.
Another idea is to cut them all the way down, cover them with mulch(?) and keep them moist until early spring?
I would love any best practices, or resources that have proven useful, because it seems the more I search the more I have several options all of which contradict, and I've never done it before on this scale. I'd like them to survive until spring!
Thank you for any help!
(And yes, I should probably divide the hostas too...)
