tapla said: I think you guys are drawing conclusions without enough information to support them. I realize it's easy to imagine a set of circumstances that would lead to someone concluding the issue is under-watering, but there is nothing in what the OP offered that allows us to make that conclusion. Just because it's hot or a desert setting doesn't mean the issues aren't related to issues brought on by soil compaction, excessive water retention. How did we imagine ourselves out of the possibility the grow medium is sand and very water-retentive, and or a large fraction of the roots have been killed by heat or rot pathogens and water usage has dropped precipitously while watering habits have remained consistent.

I'm not saying I'm right or wrong, that remains to be seen; but I am saying there isn't enough information to discount what I said - that over-watering and/or related issues (root rot, anaerobic conditions in the rhizosphere, root die-off, ....) cannot be logically eliminated from the list of potential causes until we have more information.

The question is, how do we get from "a plant is wilted and and it's located in the desert" to "it's not being watered enough"? That's like starting at "Uncle Ted was scratched by a cat last Thursday. Friday, he came down with a fever, and on Saturday he died", and concluding "Uncle Ted died from cat-scratch fever." Jumping to the conclusion in either case, based on info currently available, is coincidental correlation, a logical fallacy.

Hopefully, Leena will come up with some answers and we'll be able to use the information to test the theories.

I'd just like to know this. When was the last time you grew a plumeria tree, Al? Or any aroids? Or anything other than bonsai and plants that will grow in you yard in whatever cold zone you live in?
You are forever giving this generic blanket advice on horticulture about plants that I am willing to bet you have never grown yourself.
I usually do my best to ignore you. But in this case for this lady's plants, you are out of your area of 'expertise'. You should make it a personal policy to not give advice about things you don't grow. Especially tropical plants that need pretty specific conditions to thrive. My plumeria in Florida are all planted in the ground and guess what? My soil is all SAND. And it's not at all water retentive. You can hold a hose on the ground here for an hour and 10 minutes later dig up the spot and it will be bone dry. Plumeria in the ground here almost never suffer root rot or compromise specifically BECAUSE the soil is so well draining. I think it's unlikely the OP potted her plant in plain sand. And at temps between 40-50C, and looking at the leaf burn on the plant, it's sort of obvious to anyone who actually grows plumeria what the problem is
