Why are my beautiful mimosa trees dying?
I have loved mimosa trees since I was a child so now that I am grown I have planted them all along my driveway (yes, I live far enough out in the country so that they are not a nuisance to my neighbors). I live close to Nashville, TN. The problem is, it seems that every year I loose at least one of them and have to replace the tree or let it start the re-growth process. Now, one of my biggest and oldest trees - at least 5 years old or more - has begun to die. It was in full bloom at the beginning of the summer and looked beautiful but now it has lost over half its leaves. There are three main trunks to this particular tree - so I guess you could say there are three trees in one. There is a white foam on all three of the trunks. Should I could cut down the two “sick” trunks (trees) - the one with no leaves left on them - and leave the third trunk (tree) - which is the only healthy part left? I have seen little, tiny green bugs on my smaller trees - where some of the leaves are turning brown. I don’t want to spray the tree with insecticide at this time of year because it is full of butterflies, bees and hummingbirds. The trees are so beautiful once they get so very large and full of their flowers - it is heart breaking to see them die. I hold my breath every year!! I see wild mimosa trees around our land and town every year that always seem healthy. I grew up with mimosa trees that you couldn’t kill!! Why are mine dying? What can I do to prevent this from happening again? Thank you for your help.
