Fescue Lawn Looking Yellowish

Q: I aerated, overseeded, and scattered starter fertilizer and lime on my fescue lawn in early October. It’s up and growing well but the nice dark green color is now looking a bit yellowish. 

A: Your fescue is famished! Normal practice is to fertilize fescue three or four times between September and early April. Apply lawn fertilizer now and in April according to label directions. Use an iron-containing fertilizer (Ironite, etc) in summer. Start your fescue fertilizing again in September.
