Hi all!
My sister has some cuttings that she put into the ground last Fall, I believe...Some of the lower leaves are looking silvery, and beginning to curl. Any ideas here? All of her well established plumeria look great. Healthy and blooming. I thought it almost looked like a powdery mildew, but I've never seen it on plumeria before. Thanks for looking, and any opinions you may have.

What does it look like underneath? It almost looks like aphids or some other sucking insect?

The underside of the leaf looked 'normal'... No signs of bugs, no 'silvery' color as on the tops...

Helllppppppppp I have same issue!! My Ted chin looks like that!!

Sunburn??

I think that is an infestation of some kind, maybe spider mites. I'd treat it with neem oil (in the evening, out of direct sunlight.)

Thanks Hetty, I'll pass the info on to her...

If it is spider mites, you can tell by using a magnifying lense and you will see those little mites crawling around. Or you can wet a white paper towel and wipe the under leaves and you will see the mites as black little dots on the paper towel.

My Dwarf Pink Singapore plumerias were heavily infested with spider mites couple winters ago. ( I tried to keep them inside since they didn't loose their nice green leaves. Plus they still had blooms that I didn't want to lose.) I had to cut off Some leaves to improve air circulation, mist them everyday and wipe the underleaves with paper towel to disrupt their egg production. Then when week-ends were warmer. I would bring them outside and spray the leaves so they stay wet for some time. Spider mites didn't like the wet leaves...and that seemed to do the trick. I haven't seen those mites lately.

Spider mites! Grrrrrrrrrrr!

Thanks Gigi, I'll forward your info to her as well, so that she knows what to be looking for.

I hope this went through! Any advise is appreciated!

Thanks, Gretel

Gretel - this looks like leaf burn, ie too much time in direct hot sun.
