Hi,
here in figtrees, I have a leaf hopper/moth that is a pest - it eats the leaf surface by scratching it.
Every caterpillar that I spot is wrapped in the leaf it resides on, and squeezed in the leaf!
A bit boring, but manageable as my trees are kept at man size .
Especially for peach trees, try hanging egg-shells ! I don't know why and how it works - but it works for me !
Now I hang them in every tree; most figtrees included !
I was told that the plant of "forget-me-not" (little blue flowers) are good against pests - especially against Common Green Shieldbug. True or not, I have several that I let grow each year ...
The name of the plant states something handy : they come back year after year with little care ! Some are blooming right now :)
