Is October too late to fertilize a lawn?

In Oklahoma City, October is often still a good time to fertilize cool-season lawns like fescue, especially early in the month while soil temperatures remain warm. Fall fertilization helps grass build strong roots, store energy, and green up faster in spring. However, for warm-season lawns like Bermuda, the window is earlier, and late fertilization into dormancy can increase the risk of winter injury. The key is matching the fertilizer type and timing to your grass species and current weather. Many professional programs include a well-balanced fall application tailored to local conditions so the lawn enters winter healthier and better able to resist weeds and stress.
