I have a LOT of poison Ivy in my yard (3 acres in Michigan). Scored 53/55 (2 false positives). I’ve been trying to remove poison Ivy from certain patches for gardens with limited success. I’ve tried repeated mowing; dressing up in protective gear and ripping up roots in the wet months; covering the area in cardboard and planting over. These with for a bit, but doesn’t work well where the Ivy is well established. I’m trying to avoid herbicides since I don’t want to poison the earth. Anyone have similar experience and have any recommendations about what works for you? I’ve considered “goat rentals.” Wondering if they’re effective at ripping the roots out.
