I need help! We have a gorgeous lilac out front and I noticed one of the branches was dying, then I noticed the infamous borer's holes. ...we cut the dead branch off, but we don't want them ruining the rest of it. What do we do? What insecticide do you recommend?
They are also attacking our young red maple and another tree in our backyard.
Not sure if this is helpful too, but there is a fungus (or something) on the trunks of our trees...it's a grey/ teal color...and it seems to be spreading each year.
Any help is beyond appreciated! I don't want to lose our gorgeous trees!
