Tropicals & Tender Perennials: Plumerias love heat!, 1 by Clare_CA

Hi Dete, Louise, and Robert!

Thanks, Louise, for the compliment!

Yes, one of the greenhouses was 103 when I opened it up today, and it is 90 right now. I've seen them sit in 130 degree heat without any ill effects. If the pots are not watered well, they can get some brown tips on the leaves, but I water frequently so that is usually not a problem. You are so right that air circulation is so important, and if electricity were not so darned expensive here, I would be running three fans inside the three greenhouses 24/7. As a second choice, I open them up daily to let fresh air in. All three greenhouses are very small. This pic below shows them and shows my wavy leaf plumeria which is about to bloom for the first time.

Dete, those are lovely trees! I am still getting some lower yellow leaves both in the greenhouse and outside the greenhouse too. I think it might have to do with the low's, but I don't know that for sure.

Robert, I pop in here at Dave's about mid-day and then a few times in the afternoon as time allows. Lately, my computer gets turned off by late afternoon so I can focus on getting some other stuff done:-) You are so right that it is a known fact that a dying tree will flower prolifically in order to propagate itself before dying. I don't think that this is what is happening here. Most of my plumies developed inflo's outside of the greenhouse when the weather was still summerlike, and I put them inside the greenhouse so that they would still continue to grow and develop. The plumerias with inflo's that are outside still and that did not get a place in the greenhouse are not progressing, and I hope those inflo's will stay on and progress when the nights start to warm up. It is still in the 40's at night here. There are some leaves that look like that outside the greenhouse too so it could be that those leaves are getting ready to drop.
