If there is damage from spider mites on an Alberta Spruce tree that is 3/4 brown, once sprayed can new growth appear or is it too late to spray to save the tree?
It really depends on how badly infected the tree is, if there was a lot of damage.It's hard to tell. Alberta Spruce are super slow growers and are very finicky about their environment they grow in. If the whole tree is 3/4 brown. I really hate to say it's a "goner", but it may be looking that way.
