Is snakeroot a producer of seed?
One important warning: snakeroot is a prolific producer of seed, and once the seed starts forming on the plant, it will continue to do so and become viable even after the plant is pulled. Our harvested bundles of snakeroot are piled in areas we don’t intend to graze; often we’ll hot compost the bundles, though some sources suggest burning them. We’ve been doing this for many years, and had hoped to see a significant reduction in plant population by now. Yet the stuff keeps showing up again, which we attribute to a large latent seed bank built up in the soil over many years of non-management. Still, it’s the best approach we’ve tried, or seen suggested online.
Can snakeroot be killed?
Unfortunately, there’s no easy solution. Snakeroot is susceptible to herbicides, but this is an unacceptable option on our farm. In any case, we can’t envision a way to kill snakeroot without killing swaths of desirable plants around every little cluster of stems, and ruining the pasture for grazing. We’ve had some success with changing its habitat by opening up brushy areas to full sun, an on-going project anyway as we attempt to restore a more open savannah landscape on our overgrown farm. The best (if obnoxious) approach in our experience is to hand-weed our grazing areas.
Do goats eat snakeroot?
We’ve kept dairy goats on a snakeroot-infested landscape since 2008, but have also put a lot of time into pre-weeding our grazing areas, as our goats live full-time on pasture from spring through fall. Our goats have eaten mouthfuls at times, from individual plants or clusters we missed, with no observable effects on their kids or ourselves, the primary consumers. One Texas-based researcher we contacted years ago told us that a goat needed to eat several pounds of snakeroot to be of concern, but we don’t have further proof of that claim.

Symptoms of milk sickness include vomiting, nauseas, difficulty breathing and weakness.
