How to Fertilize Your Lawn in the Fall

Fall in Florida has its exceptional charm. While we don’t get the traditional signs of the season—leaves changing color, creating a display of gold and crimson leaves across the landscape, and people reveling in hot beverages while wearing their favorite sweaters—there are still subtle changes in the air that signals the necessity to fertilize your lawn to prepare it for the cooler days ahead.

Why Should You Apply Lawn Fertilizer During the Fall Season

The shorter days and the chiller nights in the fall provide the optimal conditions for your grass to recover from the stress of the previous summer heat—and fertilizer feeds help speed up that process.

Fall fertilizing promotes broader and deeper root growth in your grass. It adds essential nutrients to the soil, helping your grass build stamina for the temperature drop in winter. We recommend applying fertilizer in late fall, usually around late September or early October, when your grass starts to slow down its growth and enter dormancy.

This process is key to maintaining your lawn's health. It will stimulate root growth, strengthen your plants to endure the cold months, and aid in storing energy to bounce back to a healthier, greener lawn in spring.

Slow-Release Formula is the Best Fall Lawn Fertilizer

While fertilizer requirements will vary depending on the specific conditions of your soil, the best fertilizer for fall is slow-release lawn fertilizer.

Slow-release formulas are designed to provide a steady supply of nutrients to the soil over an extended period. Unlike traditional fertilizers, which deliver an immediate nutrient boost, their controlled release guarantees a more balanced and sustained nutrient availability for your lawn, preventing the risks of uneven growth, over-fertilization, and nutrient leaching.

As fall fertilizer for grass, it will help protect your lawn from winter damage, which may appear as grayish-white patches in your landscape. The affected grass may have a matted, moldy appearance, and fungi may be visible on the grass blades.

What About Lawn Starter Fertilizer?

Besides providing the optimal conditions to fertilize your soil, fall is a preferable time to cultivate warm-season grasses like Bermuda, Zoysia, and St. Augustine, when the temperatures are cooler but warm enough for grass to grow. These grass varieties can be planted either as sod or grass plugs.

Our NutriPod slow-release granular fertilizers are formulated to jumpstart the growth of your grass plugs. Each pod contains pre-measured nutrients, which you can conveniently place in the hole before planting each plug. This ensures the roots can readily access the nutrients, accelerating their growth and establishment in the soil.

How to Care For and Maintain Your Lawn in Fall

Fall lawn fertilizer application benefits your grass in many ways—it prolongs the vibrant green color of your grass in early winter, promotes root growth, pushes blade growth, and ensures stamina for the winter.

But, while feeding your lawn during fall is necessary, you should supplement your efforts with proper lawn maintenance to maximize the results.

Mow Less Frequently and at a Higher Height

Because your grass is growing slower, you don't have to mow as often as you would in summer. Mow your grass at a higher height, about 3-4 inches, to help retain moisture and protect the roots from the cold. It will also prevent weeds from infiltrating your lawn and competing with your desired plants for nutrients.

Wait After Rain to Fertilize

Fertilizing in damp soil helps facilitate optimal nutrient absorption, minimizes nutrient loss, reduces plant stress, and promotes even distribution for healthier plant growth. Wait until after a rain to apply fall fertilizer. However, ensure not to fertilize after heavy rain—allow the water to drain first for the next 24-48 hours.

Water Less Often But More Deeply

Your lawn still requires water in the fall, even when dormant. But you can reduce the frequency to 1-2 times a week, adjusting based on weather and soil conditions. Aim for about an inch of water per session to encourage deep root growth and improve drought tolerance. The optimal watering time is in the cooler morning hours, allowing enough time for the water to penetrate the soil.

Aerate the Soil

Aerating your soil creates channels that allow air, water, and nutrients to penetrate and reach the roots. It also helps break up thatch, the layer of plant debris that accumulates on the soil surface. Overall, it creates a more conducive environment for new grass growth.

Repair Your Lawn with Grass Plugs

If necessary, you can also take this opportunity to rejuvenate and repair your lawn by planting grass plugs. These small sections of mature grass facilitate faster establishment and ensure a uniform, dense lawn.

By taking advantage of the cooler weather, you allow the grass to establish strong root systems before the onset of winter, positioning it for robust growth come spring. It also minimizes stress on the newly planted plugs, increasing the possibility of successful integration with your existing lawn.

Final Thoughts

The warm, sub-tropical climate in Florida makes lawn care more manageable, especially in fall. With these insights on effective fall fertilizing practices, you can maintain a vibrant and resilient lawn year-round.
