I’m across the border, up here in Ontario. Our provincial government is extremely restrictive about ‘non-qualified’ people using chemicals. As a result, I’m exploring non-chemical options for controlling Buckthorn.
So far I’m recognizing that after cutting as close to the ground as possible, its desirable to block the remaining root from the light, so as to discourage sprouting. I’m at the point where I’m looking for everyday material and/or items that will lend themselves to being attached to the root (or ground), effectively block light and withstand a year or two of the elements. I’m aware of the “Buckthorn baggie” product, but I prefer to keep expense to a minimum and the danger of tripping on stubs to a minimum also.
Any suggestions about materials and/or experiences related to the effort are appreciated.
