Can I spray weeds in September?

Yes, September is often an excellent month to spray weeds in Oklahoma, particularly broadleaf weeds that are actively growing in the cooler late-summer and early-fall weather. Treating in September helps reduce weed competition before your lawn heads into fall fertilization and winter. This timing is especially helpful against newly emerging cool-season weeds and any warm-season weeds still hanging on from summer. As always, success depends on using the right product for your weed types and following label directions. A lawn spraying company can fine-tune September treatments around Oklahoma City’s temperatures and rainfall to get the best performance with minimal stress on your turf.
