I can’t leave Morning Glory on till the fall. They will kill the tops of the Cherry Laurels.
I’ve been following it back to the ground and cutting it to the root just above the ground. One root was 2”. But it does seem to grow back some where else. Maybe I’ll recut the root stem in the fall and poor some concentrated round up on it. Except if we sell the house I’ll let the new owner worry about it.
Each time you cut one of the main vine’s shoots, 4-10 new shoots come up from the root system to compensate.
Keep cutting it back until fall. Makes it easter to paint the leaves with the systemic herbicide, at lower levels.
You must paint the leaves; pouring it into the root system alone, won’t work. The leaves will carry the poison back to the main rootball, and kill it.
If you’re still there, just do the painting as I suggested in #109, before frost, using a wad or paper towels or small brush.
