I normally would allow mine to start dormancy and dropping leaves before moving into greenhouse. Last year I moved everything immediately at the first forecast of low 60s and kept them warm all winter. My plumeria and adenium all kept their leave all winter long. This year, because of La Nina, I am considering just allowing full dormancy and not utilizing the house at all.

As long as you don't expect a frost anytime soon, it's perfectly ok to allow them to go dormant naturally. I would make an exception for when it gets cold and wet at the same time; I know this can be an issue in Texas. 40 degrees and raining is BAD.

40 and rain coming this weekend to Houston...Sat and Sun not supposed to get higher than 50 and 60% chance of rain . It's Gumbo Weather! I am preparing. As soon as I get my chores done inside, I am going out to get that greenhouse ready for Friday's Big Move. It's actually 80+ and grossly humid right now. I'd rather stay indoors until it cools down some. I must say, looking at the trees with less leaves, it seems less cumbersome to move them already! I will remind my GF to move her 4 ft tree under cover. It's a beautiful cutting from my Riviera Rainbow and blooming right now.

drdawg said:While I was off footballing in Utah, we got down to around 40 F two mornings. All my tropical plants are still outside, including over 100 plumeria. When I returned home I found that only the Scott Pratt plants dropped leaves, and oddly enough, the leaf-drop was from the upper 1/3 of the plants, not the older, lower leaves. It appears that the Scott Pratt is far more cold sensitive than the other 15-20 varieties I have. Live and learn.

Funny you should mention Scott Pratt...

Just discovered my FIRST "home grown" inflo amongst the leaves while contemplating moving my Scott Pratt out of the Full Sun (Southern exposure) to under the protection of my front porch.. Temps predicted to hit 48 tomorrow night and later next week 41.. Thankfully _No Rain...

Believe I'm going to let nature start the leaf drop..
