Buttercup, a bright yellow flowering weed, has become a growing problem in pastures this spring. Favorable conditions like overgrazing, wet soil, and bare ground have allowed it to spread rapidly.
Although often unnoticed for years, buttercup seeds can lie dormant and suddenly emerge when conditions are right. Wet and compacted soils, often caused by livestock traffic and poor pasture rest, help these weeds thrive. Once established, buttercup can be hard to control due to its high seed production and resilience.
Livestock health is at risk. Buttercup is toxic to all animals, especially horses. It can cause mouth blisters, diarrhea, and more serious issues if eaten in large amounts. Animals usually avoid it, but if pastures are overgrazed or there's a lack of quality forage, they might eat it out of desperation.
Controlling buttercup begins with strong pasture management. Healthy forages outcompete buttercup when grazing is rotated properly and soil fertility is maintained. Avoid overgrazing and rest pastures for at least 30 days.
Keep livestock from grazing one area too long, especially in spring. Mowing after grazing can reduce seed spread, even though buttercup grows close to the ground.
In newly seeded fields, herbicide use is risky, especially with legumes like clover and alfalfa. Only a few herbicides are safe for established legumes, so consult local experts before spraying. Herbicide application before buttercup flowers in early spring is most effective. Fall treatments, combined with good pasture care, can also help.
Prevent the problem by checking hay for buttercup seeds and using clean equipment. Strengthen soil with proper fertilization and overseeding with desirable forage species to reduce bare ground.
Buttercup might look harmless, but it poses serious threats. By improving pasture health, using timely mowing, and applying safe herbicides when needed, farmers can reduce its impact and protect livestock and forage.
