Q: I need to fertilize my fescue lawn. I used starter fertilizer in September when overseeding. Should this month’s fertilizer include a weed killer or pre-emergent?

A: The general rule is that you can apply weed chemicals when the fescue has been mowed 2 – 3 times. If your grass is not thick and lush, I’d avoid the weed killer and stick with straight lawn fertilizer, applied at label directions.
