What are the worst weeds to have in Oklahoma?

Some of the worst lawn weeds in Oklahoma are those that spread aggressively and are difficult to control once established. Dandelions, crabgrass, nutsedge, henbit, clover, chickweed, and broadleaf plantain are common culprits in Oklahoma City lawns. These weeds compete hard with turfgrass for water, nutrients, and sunlight, often thriving in compacted or thin areas. Many have deep or extensive root systems and can quickly return if not treated correctly. A targeted weed control and fertilization program, timed for local seasons, is the most reliable way to keep these troublesome species in check and maintain a thick, attractive lawn around your home.
