Lawn Fertilizer Care: Expert Tips for a Greener Lawn

• When to fertilize your lawn depends on whether you have warm- or cool-season grass.
• Warm-season grass is typically fertilized from late spring through summer.
• Cool-season grass is typically fertilized in early fall and again in spring.
• Choose lawn fertilizer that matches your grass type and your lawn's nutrient needs.
• Proper fertilizer timing helps support thicker grass and stronger roots.

A lush, green lawn isn’t magic; it’s the result of smart, consistent lawn fertilizer care. Giving your grass the right nutrients helps it grow thicker, greener and stronger, so it can bounce back from seasonal stress and fight off pesky weeds and stubborn pests. In this guide, we’ll walk you through everything you need to know about lawn fertilizer care, from picking the right type of fertilizer to knowing how often to feed your lawn, plus expert tips to keep it healthy and vibrant all year.

Once you know your grass type, it’s time to schedule your feedings. Fertilization timing is key to promoting growth while avoiding over-application.

• Warm-season grasses: Fertilize once in late spring as grass emerges from dormancy and continue to feed through the summer while the grass is actively growing.  
• Cool-season grasses: Fertilize in early fall to recover from summer stress and build nutrients for winter. A feeding in early spring can jump-start green-up and an early summer application will help build density before summer stress.

Seasonal Tips for Fertilizing

• Spring: Feed emerging grass to encourage strong growth and thick coverage.
• Summer: Water consistently after fertilization to maximize nutrient absorption.
• Fall: Apply fertilizer to help cool season grasses store energy for winter recovery.
• Winter: In cold climates, a pre-frost application ensures lawns have nutrients to survive dormancy.

Environmental factors such as drought, heavy rain or unexpected freezes can impact how effective your fertilization will be. Adjust your schedule as needed to keep your lawn thriving year-round, or explore TruGreen fertilization to get pro-level results without the guesswork.

• Measure your lawn to calculate the correct amount of fertilizer.
• Leave grass clippings on the lawn for extra nutrients.
• Follow recommended schedules for your grass type.
• Consider professional guidance for tailored care. 

How often should I fertilize my lawn?

Warm season grasses benefit from spring and summer fertilization. Cool season grasses do best in early fall and in spring.

Can I overfertilize my lawn?

Yes. Too much fertilizer can burn your grass and cause stress. Follow the recommended amounts and schedules.

What’s the difference between granular and liquid fertilizers?

Granular fertilizers are long-lasting and easy to apply; liquid fertilizers act quickly for fast nutrient absorption.

Should I test my soil before fertilizing?

Soil testing before fertilizing is a great idea. Soil type and pH affect nutrient uptake. Testing ensures you apply the right fertilizer in the correct amount.
