Our winter temp hovers between 40 and 50 but there are some occasions too when it will go down to 38, but just for a night or two. It is when it starts to rain that it is more bothersome, cold and wet not good for the succulents, so drainage has to be really good. I have no space to bring in all my little ones, heheh, the containers are heavy :-)
Hmm..as for the plumeria, Hetty, am too chicken to uproot it right now,just because there is still one flower trying to come out and bloom, all the other buds went blast, but there is one trying to come out. Maybe after this little one goes downhill as well, I will uproot it and just force it into dormancy indoors to save it.
