For cool-season lawns, you want to apply your winterizer 24-0-6 Flagship right around the time your soil temperatures fall into the 40’s. You won’t be mowing anymore at that point, maybe just raking leaves, but the ground won’t be frozen yet either so there isn’t a risk of a sticking snow cover. That’s the key: soil temps in the ’40s.
For those of you who do not get snow, we suggest winter fertilizing. Our strategy is to go higher in potassium because that is the macronutrient that helps lawns through stress. The best way to get it is by using the 7-0-20 Stress Blend. It’s 20% potassium, and the 7% nitrogen is 100% slow release so it’s isn’t going to do anything crazy to push growth as we move into winter. Apply this after your final mowing of the season.
