ash tree advice
we have 2 very large ash trees quite a bit taller than our old 2 1/2 story home. One is a primary source of shade, the other would, of course, be be a major loss. its just beautiful with our grandchildren's swing on it. we have another younger one reaching to the second floor windows, but very close to our home. we are at a loss as to what to do. I was in Osage Beach, Mo a week ago and there were those bugs everywhere laying on the ground in mounds. So I know their coming is only a matter of time. Should we plant something that is fast growing near these trees and hope for the best? What would be a good tree to put in its place? Also we planted a Russian red leaved maple by our horses last fall in memorial of my father in law. Now I find out these leaves are poisonous to horses. The tree is 8-10' tall now. Is it too late to replant? would it be better to replant it now, later or would it be too risky to try it at all?
