I forgot about my begonias! the rhizomeous kind with hairy leaves. Would they do ok in the cool and dark? my basement is very very cool and dark. I've two orchids in bloom and three that are "resting"- no leaves but alive.
I would think so... I would think that with lower temps, indirect light, all plants grouped together and tented, as Al suggested in your other thread, and watered well before you left... they should fare ok... I might even go so far as to set up some kind of drip or wicking system to help... link with picture below.
It would be better if you could find someone to plant sit for you. Perhaps someone else has a few other suggestions to add...
