my problem is that my yard backs up to something called a "native growth area". that would be wonderful, except that the area is completely overrun with (non-native) himalayan blackberry. and because our yard has such sparse grass, the "lawn" is now *full* of blackberry sprouts. i've been trying to get them with a scuffle hoe, but an acre is a LOT of land to hoe.
do i have any hope of keeping my yard free of these invasive vines? i can't kill anything in the "native growth" area, so they'll constantly be sending out runners and spitting out seeds, and whatever else they do. i've read that they can reproduce if you just drop a branch on the lawn. is there any hope for me? i've been having nightmares about "Still Life with Woodpecker", by Tom Robbins.
