Hi, everyone.
I'm new to permaculture--so new, in fact, that so far I've only read about it; I haven't actually planted anything.
I have a groundhog / woodchuck problem. So far, I've successfully used a chicken-wire
fence to keep them out of my vegetable patch, but I'm planning to expand the patch and am loath to expand the
fence as well. I could, of
course, trap them, shoot them, or gas them (the last only with difficulty, as their burrow entrances are somewhere amid many piles of junk in the 1' crawlspace under the barn). But I was inspired by
Toby Hemenway's story in "Gaia's Garden" about keeping
deer out of his
yard using a thorny hedge, and I wonder if anyone here has any
experience with similarly benign, low-tech methods of woodchuck control.
I live in Maine, zone 5A/B.
Many thanks,
permanoob
