Crabapple bush infested by Cedar Apple Rust
We have a crabapple bush that, from description on your website, appears to be Apple Rust. Is there any benefit of treating it now as against waiting until spring?
Oakland County Michigan
We have no cedar trees around. However, I will search and see if I can see any indication of any other trees being affected. If I do find any galls now or later, should I be treating the tree/bush?
