I live on a hot dry windy bluff in SLC Utah area.

I have a cherry tree and a barkwood elm tree. I have only had them a few summers. Last year I took them to a trimmer guy and he sprayed something on the leaves. I am not sure it was only water as we had a language barrier. I think he indicated that it was some kind of sealer?

I have some wilt pruf here but on the label it says not for "slow growing dwarf plants"

I did a search for wilt pruf and only 2 threads came up so I am thinking it is not commonly used?

I will wait to hear what you guys have to say.

Some might not think it is a problem but we get this hot super strong wind out of the desert that blows for days
