How to Safely Fertilize Your Lawn in Spring

Spring Fertilizing

Spring is a season of growth and renewal, making it the perfect time to give your lawn a healthy head start. Fertilizing in early spring helps your grass recover from winter stress and encourages strong roots and vibrant green blades. But like most good things, too much fertilizer—or applying it the wrong way—can do more harm than good. Here’s how to safely and effectively fertilize your lawn this spring.

Know Your Grass Type

Before anything else, identify what kind of grass you have. Cool-season grasses (like fescue and Kentucky bluegrass) benefit from early spring fertilization, while warm-season grasses (like Bermuda and Zoysia) typically need nutrients a little later, once temperatures rise consistently. Applying fertilizer at the right time for your grass type is key to safety and effectiveness.

Test Your Soil First

A soil test tells you exactly what nutrients your lawn needs—and what it doesn’t. Over-fertilizing can burn your lawn and contribute to runoff, which harms local waterways. Soil testing kits are affordable and easy to use, or you can have a professional handle it.

Choose the Right Fertilizer

Look for a slow-release, nitrogen-rich fertilizer formulated for spring use. This ensures your lawn receives nutrients gradually, avoiding a sudden growth spurt that leads to shallow roots and higher water needs. Choose a product labeled for your specific grass type for best results.

Using a pre-emergent is also a great way to fight weeds and crabgrass in the summer. It works by stopping weed seeds from germinating, giving your lawn a head start before invasive growth takes over.

Apply It Correctly

Use a broadcast or drop spreader for even coverage and avoid overlapping passes. Always follow the product label instructions to avoid overuse. Apply fertilizer when the ground is moist but not soaked—ideally after a light rain or a gentle watering. Never fertilize before heavy rain is expected, as it may wash away your hard work and pollute local water systems.

Clean Up and Water In

After application, lightly water your lawn to help the fertilizer soak in. Be sure to clean fertilizer off driveways, sidewalks, and other hard surfaces, as runoff from these areas can contribute to environmental harm. Store any leftover product safely, away from children and pets.

Timing Is Everything

A good rule of thumb is to fertilize in early spring—once the grass has started growing but before summer heat sets in. Too early, and the nutrients go to waste. Too late, and you risk burning the grass or encouraging weed growth.

Fertilizing your lawn in the spring is a smart step toward a lush, green yard—but only when done with care. With proper timing, the right product, and safe practices, you’ll set your lawn up for a season of healthy growth.
