My Plumies are getting as much sun as I can give them in my shady yard, without taking up space for the cars on the driveway. They get 6 hours of bright summer sun slightly mottled sunlight by the Wax Myrtle tree next door at 4 pm BUT their pots are almost always in the shade. Is that ok?

Well right now, we're in the middle of a heat wave, temps most everywhere in the southwest are in the 88-115 degree range. If your plumeria are in those black plastic 1-5 gal. pots most of us use, right now having roots shaded might nt be a bad thing, temps in black plastic pots can get hot enough to bake the roots of our plants. Long as the roots aren't cold and wet. For plumeria, cold and wet conditions cause problems.
After the heat wave passes (hopefully, soon!), you could move your plumeria onto raised wooden benches made from wooden boards laid across concrete blocks, to raise your plumeria up to a warmer spot in any sunlight available, preferably with at least 6 hours sunlight

Thanks. They are in light plastic pots. I like your idea of raising them to get their feet warm. Probably should do that in the fall. "Cold" is definitely not a problem in the summertime here in Houston. We never expect relief from the heat until late September. In the mean time, we water and water well.

Your plumeria are in light -colored pots...? Where did you find those, if you don't mind my asking? These last few days, I've really wished I had some of those, instead of my black ones!

Cyra, I have never spray painted any of my large, black plastic pots, but I have painted many of my composite ones. The composite ones are more ornate though were an ugly gray color. I spray painted them off-white and have three different size ones grouped on my front walk-way. Krylon makes spray paints specifically formulated for plastic, and you can find these at any big-box store, such as Lowe's or Home Depot. The pots I have were painted three years ago and they look as good today as when they were painted. I would think this product would work equally well on those black plastic pots.

We have stores called Garden Ridge Pottery. They have a nice selection of plastic pots in all colors. You can find them regularly at Lowe's, Walmart etc. They are pretty common around here. I use a smaller one for the dog's water. Obviously you have to drill your own drainage holes. I like plastic pots for my Plumeria because they are lighter to move indoors for the winter. It works for now. IDK what I will do when they become huge trees? One is already 8 feet tall and branching out way over my head. The branches have already grown 8" this year. Might have to think of alternatives for that one soon.

Thank you, all for the good suggestions...those black plastic pots are downright lethal in this heat..!

Updated :
Baked my beautiful cutting ("Generosity ") in it's pot, it seems, though it might recover. All but it's center growth wilted and dropped. Guess I didn't move that pot out of the sun fast enough!

Cheryl, I usually take a cutting from my larger plummies, and then give them away to whichever coworker has their Birthday first. These days I'm trying to only acquire slow -growing compact, dwarf, or miniature plumeria. Only thing is, there's not much of a selection of these (mainly) obtusa crosses...yet. (Divine, Dwarf Watermelon and Thumbelina are good steps in this direction, I hope plumeria breeders continue to provide the public with a larger selection of fragrant minis!)

That is definitely something a lot of growers are working towards.
Don't forget, in addition to the few true dwarf varieties there are also quite a few 'compact' ones such as Penang Peach.

Yes, thankfully, but even compact varieties eventually outgrow my available space, and end up as holiday gifts. Wish there was a way to retard their growth, and still retain their bloom size & fragrance. (Smile) Plumeria .....bonsai?

it has been tried.
