On the boundary of our property are trees approaching 100 feet high. Some are badly infested with ivy to the extent the canopy is almost solid and the trunk and branches are twice their true size, blocking out a lot of light.
The ivy is as thick as my arm at ground level. Clearing it from the tree is not practical but would cutting it at the ground have any effect? Is there anything I could put on the cut ends that would get sucked up and poison the plant higher up?
