Dear all,

I have a frangipani tree with some kind of problem. I am not knowledge enough to identify what the issue might be. Can someone help out?

Please see attached photos of over/under leaves.

Thanks for all comments.

Regards, M

are they ants? I have a citrus tree that tends to get colonized by ants and their little honeydew-producing aphids, the leaves get dirty-looking just like that. Look at the stems, undersides, places where the little buggers can hide.
I have cleaned the leaves with soapy water (not recommended, but it was effective), blasted the darn thing with water,, and sprayed with a garlic-oil-soap solution, but in the end what worked was really fertilizing the tree and putting ant barriers (vaseline-smeared aluminum foil collar on the trunk). I still find some icky leaves but the tree is a lot happier.

Thanks, @Tereza I will have a closer look to see if it's ant - but I don't think so. I have never seen any ants on the leaves.

Do the underside of the leaves look sort of like bubbles or raised spots?

If so you might have galls. Galls are caused by tiny wasp-like insects and mites.

The second photos in the post is the underside of the leaves. Does it does look like galls?

Thanks, Mark

That is what I thought it looked like. Being able to see the leaf in person would be better though not possible.

Basically you need to safely dispose of all infected leaves.  Also rake up any leaves that are on the ground.

I was not able to find out anything else regarding a natural cure.
