I normally hit the lawn with weed and feed pellet fertilizer/herbicide in October. I forgot, and we've had one small snowfall. Temps are lingering around freezing or a little below right now, but temps are supposed to be close to 45 later this week. Is it advisable to spread fertilizer this late in the season? I've got a good stockpile, so if it won't do any harm, I plan to do it. Can anybody offer some thoughts here?
