I last fertilized in mid may with a regular scotts fertilizer , no add-ons, I want to put down a weed and feed but do not want to "overfertilize" and burn lawn... is it OK to do this now (june 21st) or should I wait?

(btw---did not do weed and feed earlier due to laying down seed in april/may)

Thanks

I wouldn't think it necessary to fertilize so soon unless too much rain washed it away. But the 1st thing I'd do is read the label - on both pkg if dif brands. It should tell the frequency.
