“If you have a lot of tansy plants and are feeling overwhelmed, focus first on areas where grazing animals are present or along fence lines to help with your neighborly relations. Pull flowering plants and dispose of them as trash or pile them up away from grazing animals and then burn them when allowable. If plants are already going to seed, cut off the seed heads and dispose of as trash. Try to avoid spreading seed further. Follow up the next spring by pulling emergent rosettes when the ground is still wet… Avoid overgrazing, reseed good pasture grasses as needed, and implement rotational grazing practices when possible to rest vegetation over time.”
