We have 7 mature elm trees on our city lot... and probably 15 juveniles that I regularly chop down. These 15 trees are trees growing where trees shouldn't grow... between the house and driveway, in the middle of flower beds, and HERE:
... in the middle of our shrubbery. The light colored branches are the elm. I have chopped this tree down at least 3 times. The last time I even carefully dabbed stump killer on the cut stumps, to no avail. It takes about 3 months to create the kind of growth you see in the picture... if I miss even a week of chopping down suckers, it's over. I just spent 2 hours chopping down this and the rest of the elms invading our shrubs... and dabbed a bit more stump killer on, but I suspect that it won't work this time, either. I like the shrub, and don't want to kill it. Any suggestions?
