As Union County farmers know, summer is a critical time for managing pastures—and one persistent challenge is the spread of broomsedge. Broomsedge is a true grass, not a sedge. Broomsedge is also sometimes called “sage grass” but it falls short of the mark as a forage grass. Cattle will eat it but for only a short period in the spring when the new leaves first emerge and there is nothing better available. Once the perennial, clump-forming, three-foot-tall, erect growing stems emerge in early summer.

This wiry, golden grass may look harmless, but it’s a indicator of poor soil health and declining forage quality. Broomsedge is a warm-season perennial that thrives in acidic, nutrient-poor soils. It often takes over when cool-season grasses like tall fescue and orchardgrass are weakened by overgrazing or improper mowing. Unfortunately, there are no selective herbicides that target broomsedge without damaging your forages, so a long-term, integrated approach is key.

The first and most important step is a soil test. Broomsedge loves low pH and depleted nutrients—especially phosphorus and potassium. Applying lime to raise the pH above 6.0 and fertilizing according to test results can help. With consistent care, a healthy stand of tall fescue can outcompete broomsedge over the course of several years.

Proper grazing and mowing practices are also essential. Avoid grazing or mowing below 3–4 inches to allow forage plants to store energy and regrow stronger. This gives them a better chance to crowd out weeds. During the summer, while cool-season grasses are dormant, mowing broomsedge can reduce seed production and weaken the plant. July and August are ideal times for this practice.

If broomsedge has taken over more than half your pasture, it may be time for a full renovation. For lighter infestations, overseeding can help thicken the stand and push broomsedge out. When broomsedge grows taller than your forage, a rope wick applicator can be used to target only the taller broomsedge minimizing damage to the rest of the pasture.

With patience and proper management, Union County farmers can reclaim their pastures and boost productivity. Broomsedge may be stubborn, but it’s no match for a good plan and a healthy stand of grass.
