Remove wisteria vines from up in Holly shrubs. I will copy a detailed description of the process reTo remove wisteria from a holly shrub without harming it, you must sever the wisteria vines at the base and carefully apply an herbicide to the cut ends. Wisteria is aggressive and will regrow from its roots, so this "cut and treat" method is the most effective way to kill the root system while protecting nearby plants.
Step 1: Cut the wisteria vines
Gather your tools. You will need hand pruners for thin vines, a pruning saw for thicker vines, and heavy-duty gloves to protect your hands from both the wisteria and the spiny holly leaves.
Find the wisteria's root. Follow the main wisteria vines down to the base of the holly and locate where they enter the soil.
Cut the main vines. Using your saw or pruners, make a clean cut through the wisteria vines 6 to 12 inches above the ground. This ensures you have a stump to treat and creates a gap between the root system and the upper vines wrapped around the holly.
Wait for the upper vines to die. Do not try to forcefully pull the vines out of the holly, as this can damage the shrub. Once the vines are severed from their roots, they will eventually die, dry up, and fall off naturally.
Step 2: Treat the stump with herbicide
Select an herbicide. A concentrated glyphosate or triclopyr herbicide is recommended for painting onto cut wisteria stumps. Both are effective at killing the root system, but they require. . . |
