I live in Florida and I noticed that about 3 of mine grew too much and should be repotted. I plan on doing it tomorrow with just a week feeding to stabilize plant but not to encourage it. Paula

I would transplant it. Just not too much bigger a pot than what you might have it in. I imagine you will be heading into cooler nights there?

It still gets up to mid 80's during the day and high 50's at night. My new pot isn't that much bigger around but is deeper. I was just in Hawaii and saw some adeniums that were huge and beautiful. Don't think mine will ever get that big :(.
