Dull Fescue Has Weeds – Should I Fertilize?
Q: I have a fescue lawn and it’s taken a beating with the dry, hot weather. It looks a bit dull and there are a few weeds creeping in. Should I fertilize?
A: Fertilizer isn’t the answer. With daytime temperatures in the 80 s and 90 s, it’s just too hot for fescue to grow well. Nights are not cool enough for fescue to recover from daytime heat. I think you could apply Ironite now to make the grass green with soluble iron. Irrigate to avoid wilting, but only to supplement natural rainfall, not to exceed one inch of water per week.
