For those that spray trees, is it considered OK practice to spray trees preventatively annually/biannually (with like a triple action plus spray or something)? Or is it considered bad practice to "preventative spray" a tree that is in fine shape, unless one is convinced theres a real good chance of the trees getting a disease or insect infested. May sound like a dumb question to some, but I'll ask it anyhow.
(I ask because I did some spraying some austrian pines for tip blight, but there also is norway spruces around that are just fine, but I thought I might start spraying them(mainly because those in charge asked me to) annualy for a preventative of fungis, bugs... )thoughts?
