It's that time of the year again when you should consider putting down a preemergence for winter weed control. I usually recommend applying a preemergence between August 15th and September 15th. Why such a big gap in dates? Weather dictates everything we do for weed control. If you have had a dry summer I would recommend applying your preemergence more towards the September date, but if you have had a wet summer like we have had this year I would go with the August date. The more rain you have had will more than likely cause early weed germination for winter weeds. Poa is one of the worst possible weeds you can have and it loves cool and wet weather. So stay ahead of those pesky weeds and apply a preemergence for a nice clean lawn all winter long.
