Dealing with regrowth from aggressive species after romoval is a challenging problem. Our most implemented procedure is first warning the client that regrowth is a possibility, even a probability, that will require future treatment.

What we do is try to schedule the removal during the most active part of the growing season as possible. On completion of the base cut we do cut the grove in the cambial zone to a depth of 3/4 to 1 inch deep around the full circumference of the stump, but instead of applying a herbicide we carefully and IMMEDIATELY apply our chainsaw fuel mix.

This mix is absorbed rapidly on a fresh cut and we have had good results on what we refer to as a shock response kill. We generally allow this situation stand for at least 3 weeks prior to grinding out the stump. We have not experienced any translocation related toxicity to date.

If regrowth does happen of individual sprouting, the best method is to pull the root, which with the stump removed is not as big of a deal. (Many clients have us do this at the time of grinding the stump.) If that is not possible a systemic herbicide for leaf application is then recommended. (We inform the client that they need to allow the regrowth, spray, wilt, then cut; rather than cut off the growth then spray.)
