When should I remove my purple-leaved oxalis into green-house?
I heard that the purple-leaved oxalis would die in the winter, and
would revive next spring from its tuber. However, I have an access to a
green house in my institute. So ,I hope I can move my lovely oxalis
into green house as the winter comes. But when ? Or rather , under how
many degree Celsius, should I remove it?
Thanks a lot!
