How to get rid of:
It is often more effective with tall herbaceous plants, such as
grasses, and some woody weeds to first slash the area and only
spray the re-growth. Allow 3–4 weeks for new lush growth and
then spray. Most chemicals works best when plants are healthy
and actively growing. By removing dry stems and forcing the plant
to put on new growth the uptake of herbicide will be improved.
