Hello everyone,

I am relatively new to growing plumeria. I got all three of these cuttings last year and got them to where they were looking really good. They are Aztec Gold and Cotton Candy. I am in a zone 9 I believe (Fresno CA) and the last few days have been 105-110 degrees. I have been fertilizing with Grow More SeaGrow Bloom 4-26-26 and Grow More Hawaiian Bud 5-50-17. The SeaGrow Bloom has:

Nitrogen- 4.0%
Phosphate - 26.0%
Potash 26.0%
Boron - 0.02%, Copper - 0.05%, Iron - 0.3%, Manganese - 0.15%, Magnesium - 0.5%, Molybdenum - 0.0005%, Zinc - 0.05%

I think I am giving them a decent amount of food and water but not too much water. I am debating if I should move them under my patio until the heat of summer cools down a bit. I have 5 new cuttings coming from Thailand soon and I really want to figure out what is going on with them. They are yellowing and burning and one of them has a weird wrinkled leaf set coming out. Please give me a hand with this one! Thanks everyone. See pics. Group hug

I would move them. Last summer we had 2 weeks of near and over 100ยบ. I quickly moved mine under a tree. They love the heat but often constant direct sun can be brutal, as you found out. Give them a good drink, too. That kind of heat takes a lot out of them!

Agree with Cheryl, I would provide some shade and step up watering. If all of them are rooted and leafing properly already, it will not mind daily watering especially when our temps are going always beyond 100F for several days. I have to do that to my Plumerias, in fact I even spray the entire stem, it dries out too fast anyways. Our humidity is so low...it needs all the humidity it can try to have. I water early in the day before the sun hits them, direct to the root zone. It loves water when temps are very hot. My plumerias thankfully get the shade of our city trees, so it helps a lot during heat wave days.

Have seen them growing so well in my old homeland and we get over 22 typhoons there. The consistent thing that they have there too is high temps and high humidity. So don't be afraid to water them more during summer and during heat wave.

Thank you so much guys! I guess I confused the "they love heat" to blast them under full sun. I was too excited to push them hard this summer to try and get an inflow to show up.

Should I put them under shade cloth or just under the patio overhang for now? Thank you again.

Hi Tim! Yes, you can put them under your patio overhang for now. Or if you have a way to position them facing eastern sun then getting shade in the afternoon where we get the more onerous heat duration. Your area is about 5 to 6 degrees hotter than ours. Got to endure our Central Valley heat Rolling my eyes.

Slow down on fertilizing during heat wave days, you might just end up with fertilizer burn on your plant and it will show on the leaves. It is normal for some lower leaves also to drop during heat wave days and to drop some leaves especially after being shipped in from elsewhere, then undergoing repot, so plant is having a lot of shock adjustment to its growing environment. Most plants also just go in some slow down once temps are in the 100F mark, and will resume growing once temperatures return to better levels. But even in slow down, the roots are drinking, so water very well.

Welcome! MrWhite

I know what your going through. I just got done moving mine under the eve of my house roof on my front patio.
They get morning sun for about 1-2 hours and shade the rest of the day. I have positioned the pots to where they get full sun all day. I cut the burnt leaves off and let the Plumeria focus it's energy on new leaves instead of ones that will die anyways.
Nice to see another member near our area.
