Feed Smarter This Fall
Fall fertilization sets the foundation for next spring’s green-up, but not all fertilizers work the same. Beyond timing and technique, the nutrient sources you choose make a big difference in lawn performance and color. Two key ingredients: slow-release nitrogen and iron, deliver lasting benefits for cool-season grasses like tall fescue, ryegrass, and Kentucky bluegrass.

Fall Lawn Fertilization: When, Why, and How to Feed Your Lawn Before Winter
Why Choose Slow-Release Nitrogen
Unlike quick-release nitrogen that causes a short flush of top growth, slow-release nitrogen feeds the plant gradually. This steady delivery:
-
Supports consistent color through fall and early winter.
-
Encourages deeper root growth instead of excessive leaf production.
-
Minimizes nutrient loss from leaching or runoff.
A balanced fall fertilizer such as 19-0-10 provides sustained nitrogen along with potassium for root strength and improved stress tolerance.
The Role of Iron in Turf Color
Iron doesn’t replace nitrogen, but it amplifies results. As a vital micronutrient for chlorophyll production, iron deepens green color without increasing mowing frequency or stressing the plant. When combined with slow-release nitrogen, lawns retain a rich, healthy hue longer into winter and green up faster in spring.
Pair Fertilizer with Weed Control
Early fall is also the ideal time to control broadleaf weeds. As weeds channel nutrients down to their roots, post-emergent herbicides are more effective. Applying a weed control product alongside your fall fertilizer creates a dense, uniform stand of turf that outcompetes unwanted plants next season.
