The majority of our time so far has been spent manually pulling out the barberry, using a rock bar to pry it out or wrapping a sling around the base and using a winch to rip it out. These methods are effective, but are a lot of work and very time consuming. We decided to look for other approaches and came up with torching.
Torching is used sometimes in place of weed whacking.
Since the stems of barberry are pretty thick, we start off by clipping the base
of the bush before actually torching. In order to completely kill the bush, the
torch must be held on the plant for about 30 seconds or more. We are not 100%
certain this method works, so a test grid was set up. That way in a year we can
come back to see if torching was effective. Overall I would say torching took about
the same amount of time as using a rock bar, and it should not be done on a dry
day. However, it was much less strenuous and would be a good manner for getting
the isolated bushes that surround the dense thicket of barberry.
