Why You Should Fertilize Your Lawn in November

Benefits of Late Fall Applications of Fertilizer

1. Root Strength and Winter Resilience: A lawn’s survival and resilience through winter heavily depend on the strength of its root system. Stronger roots can better withstand cold temperatures and potential frost damage.
2. Promotes Early Spring Green-Up: “A final fertilizer application is recommended because it sets the stage for a lush, green lawn in the spring,” says Dr. Koch. Fertilizing in November sets the stage for active growth, especially as temperatures warm up in the late spring. Unlike a lawn left unfertilized in the fall, a well-nourished one will turn green faster, often with fewer weeds and a healthier, more even color.
3. Long-Term Nutrient Storage: Late fall fertilization enables your lawn to absorb and store nutrients that it will utilize through the dormant winter season. Grass plants that store nutrients will experience a better growth stage in the spring, and be ready to withstand the heat and other summer stresses. According to Dr. Koch, “A good fall fertilizer prepares your lawn for what’s to come, giving it a head start that’s hard to beat during the cold winter months.”

Choosing the Right Fertilizer for November Application

Fall grass fertilization will require you to choose a product suited to fall’s unique needs. "Applying a type of fertilizer geared toward strengthening roots rather than boosting top growth ensures your lawn conserves energy where it’s needed most – in the root system – for a healthier overall structure," highlights Dr. Koch. He recommends using products specifically formulated for this time of year, like Scotts® Turf Builder® WinterGuard® Fall Lawn Food, an option designed for enhanced rooting that supports improved resilience during winter dormancy. It's crafted to work well on any grass type without watering and can be applied on wet or dry lawns, so don't be concerned whether or not heavy rain is in the forecast.

Tips for Applying Fertilizer in November

Applying fertilizer in November is slightly different from spring or summer, where products are more likely to use slow-release nitrogen. Here are a few tips to maximize your late fall fertilization:

• Timing is Key: Aim to apply fertilizer just before the ground begins to freeze. This allows the roots to absorb nutrients before entering the deepest phase of dormancy.
• Spread Evenly: Use a broadcast or drop spreader to distribute the fertilizer evenly, avoiding patchiness and ensuring all parts of your lawn get adequate nutrients.
• Don’t Overdo It: Fall fertilizers are typically higher in potassium and phosphorus for root health. Be cautious not to over-apply, as this can cause fertilizer burn which harms your lawn rather than helping it.

Can you apply lawn fertilizer over snow?

No, it's not recommended. Wait until it melts! If you decide to spread fertilizer on snow you'll simply increase the runoff risk, chance uneven absorption, and, simply put, waste your money. If the roots are frozen, they won't absorb the nutrients. Use it before the ground is frozen, or save it for next year.
