I live in zone nine; what month is the best to plant my plumeria cutting?
It will not survive in zone 7. This will need to be a container plant that you bring in once it starts to get chilly.
These articles will help you to grow the shrub:

I live in Annapolis , MD and must bring my (3 of them) over 6 foot tall plumeria inside ( lower level of split foyer) for the winter. Their tall size and width may it increasingly harder for my adult son and husband to carry them in. Aside from stripping their leaves, can I top or trim off the larger tops and root the whole piece now or wait until spring? Even tho it is the middle of October, our weather has been pretty warm and some of the branches are still blooming. Thank you!
Plumeria cuttings root best in spring and summer. If it is still blooming, you sure don't want to prune anything now.
I usually see cutting size as 12 to 18 inches. One in a "V" shape may take a long time to root, increasing its chances of stem rot. But it sounds like you have branches to spare, so it wouldn't hurt to try. If you can't wait till spring to prune, use a light and heat mat to help it along through the winter.

It would get plenty of sun, middle of the lawn. i wonder about winter, which doesn't go below 35, is still too cold for it. It is doing well in a pot. We get temps of over 100 degrees in summer sometimes. I think last year I put it in the garage when it was going to be cold and frost.
It's best not to expose it to less than 40 degrees F. One hour at 32 degrees F can kill it. You can always plant it in the ground in spring, either in or out of the pot, then dig it up in the fall and bring it in. Some people leave it in the ground then cover it when temps plunge, but you sure wouldn't want a freeze to sneak up on you and lose your plant. You can leave it in the garage all winter and let it go dormant. Or leave it in the house and let it go dormant.

Hello, about 4 weeks ago i transplanted two - 5 ft plumeria trees sharing a pot to their own pots. When i did the transplant it was very hot so i made sure they had plenty of water but the pots drained well. They both seemed to go into shock, with droopy leaves and i was hoping they would bounce back but i've noticed the small branches at the top are soft and not hard like my other plumeria. I just realized i had planted these 2 plumeria in pots that i had plumeria in prior and lost those plants to root rot. Could that be the problem? If so, what is the best remedy? New pots & new soil? Should i use some fungicide? Please help! Thanks
Just to be on the safe side, I would repot in new soil and new pots like you said. The heat may also have something to do with it. Plumerias are best repotted in late winter or early spring.
It could be stem rot starting. Root rot usually starts from the bottom and moves up the trunk. I would hold back on the water, you just may have overwatered. Do not water again till the soil is dry.
ne it? If I need to prune the branch, where do I make the cut?
Here is information on pruning as well as winterizing your plumeria.

.The leaves have fallen off and now the tip has turned black. Is that typical or do I need to do something?
No, it's not typical and could be black tip fungus. You can treat it with a fungicide. Once you get the plant back out in the sun in the spring will help. Be sure not to overwater your Plumaria during the winter, if at all (depending on what school of thought you are following).
I have ordered several cuttings from Plumeria plants, I need to know how large the pots should be for planting indoors . I live in Ocala, Florida US
They do much better outside. For pot size it depends on your cutting size. A general rule is to use 1 gallon pot size for each foot of branch/trunk. So if your cutting is 12 inches, use a 1 gallon pot. The nursery pots are recommended because they have excellent drainage holes.
