UREA 46-0-0 is an all Nitrogen fertilizer, which is perfect for a winter fertilizer (winterizer). The best time to apply Winterizer around here is anytime between Halloween & Thanksgiving.. when you cut your grass and put your lawn mower away for the season, that's an easy rule of thumb to apply winterizer if you haven't already. 46-0-0 covers 15k-20k sq ft per 50lb bag (do not apply 50lb bag over 10k sq ft) Keep your spreader open 15-20%. Less is more, don't go too heavy, 46-0-0 is a strong dose of Nitrogen. It does cover more than most bags
