We currently have a tree of heaven growing beside our house. Previous owners only cut the tree back causing it to sprout onto our neighbor's property. Attached are closer photos and there seems to be multiple root systems growing near the foundation. It seems like physical remove would be impossible at this point. Is glyphosate our best solution? The tree is so tall that at this point I'm worried that surrounding plants would be affected since I believe glyphosate best applied to the leaves. Would cutting the tree down and applying glyphosate to the future sprout leaves help reduce overspray or is there a better method?
