Frequently Asked Questions (FAQs)
1. What is a good fertilizer for the winter?
Cool-season grass will benefit from fall feeding. You can use a winterizer or another fertilizer as long as it contains both nitrogen and potassium. Or supplement your lawn throughout the season with potassium from organic sources.
2. Should fertilizer be applied in winter?
Don't fertilize too early! During the winter months, grass is likely dormant if you haven't been irrigating. When you fertilize too early in spring—meaning it's still winter— you're providing nutrients before the grass has broken dormancy. It won't be able to immediately take advantage of the nutrients you provided.
3. Is it OK to fertilize lawn in winter?
After you've opened up your lawn, it's a good time to fertilize with Scotts® Turf Builder® WinterGuard® Fall Lawn Food. Fertilizing your lawn gives your grass the essential nutrients it needs as it prepares for winter. The grass roots absorb and store the nutrients during the winter months.
4. When should I apply winter fertilizer?
The best time to apply a winterizer is after the grass stops growing in the fall, while it is still green on top and active below the surface. In most parts of the North, this will be sometime in mid-late November, or even early December.
