It is only practicable on relatively large single-stemmed plants.

Only the lower concentrations are labeled for use in landscaping.

Girdling alone is often ineffective for long-term control of woody invasive species due to their ability to regrow from the root system.5/5.

Stumps should be cut as close to the ground and as level as possible (Figure 2) so that applied herbicide does not run off. Make a series of downward cuts into the tree trunk using a hatchet, leaving the cut portions of the trunk (the chips) connected to the tree.

Make these cuts all the way around the circumference of. Jul 25, Frill or Girdle Treatment: Make a single hack girdle or"frill" of overlapping ax cuts through the bark completely around the tree as close to the ground as feasible.
