How to Fertilize Your Lawn Before Winter Dormancy

As cooler temperatures set in and your lawn begins to slow its growth, proper fall fertilization becomes one of the most important steps you can take to maintain a healthy yard. Many homeowners assume that once grass growth stops, lawn care does too—but that couldn’t be further from the truth. At Waco Landscapes and Irrigation, we know that feeding your lawn before winter dormancy sets the stage for lush, green growth in the spring. Here’s how and why to fertilize effectively before the cold arrives.

1. Understand Why Fall Fertilization Matters

Even when your grass appears dormant, its root system continues to grow underground. A well-timed fertilizer application strengthens roots, boosts nutrient reserves, and improves resilience against cold temperatures. The right fall feeding helps your lawn recover faster in the spring and prevents patchy, weak growth. It’s essentially your lawn’s “winter meal”—fuel to sustain it during the dormant season.

2. Choose the Right Fertilizer Formula

For Texas lawns, especially warm-season grasses like Bermuda or St. Augustine, use a fertilizer that’s high in potassium (K) and moderate in nitrogen (N). Potassium enhances cold tolerance and root strength, while a smaller dose of nitrogen supports mild green-up without overstimulating growth. Look for blends labeled as “winterizer” or “fall lawn food.” Avoid fertilizers heavy in nitrogen alone, as they promote top growth that can be damaged by early frosts.

3. Time Your Application Correctly

The best time to fertilize your lawn in Central Texas is in late fall—typically between mid-October and early November—before the first frost but after temperatures have begun to cool consistently. Applying fertilizer too early may encourage excess growth, while applying too late limits nutrient absorption before dormancy.

4. Mow and Water Before Application

For best results, mow your lawn to a moderate height and lightly water it a day before applying fertilizer. This helps nutrients absorb more evenly and prevents fertilizer burn. Spread the fertilizer evenly using a broadcast or drop spreader, following manufacturer instructions for coverage rate. After application, water the lawn again to help nutrients penetrate the soil and reach the root zone.

5. Aerate for Maximum Effectiveness

If your lawn soil is compacted or high in clay (common in Central Texas), consider aerating before fertilizing. Aeration allows air, water, and nutrients to reach the root system more efficiently. This simple step can dramatically improve fertilizer effectiveness and overall lawn health heading into the winter months.

6. Combine Fertilization with Weed and Pest Control

Fall is also a good time to tackle broadleaf weeds and prevent pest activity before winter. Applying a pre-emergent herbicide or pest treatment after fertilization can protect your lawn from unwanted competition during the dormant period, keeping it healthy and clean when growth resumes in spring.

Give Your Lawn the Advantage This Winter

Fertilizing before winter dormancy isn’t just maintenance—it’s an investment in your lawn’s long-term vitality. With the right timing, formula, and preparation, your grass will emerge greener, thicker, and stronger when spring returns.
