Summer lawn fertilizers can help keep your yard growing strong through backyard cookouts, outdoor chores and long stretches of hot weather, but the right feeding plan starts with your grass type. Warm-season grasses such as Bermudagrass, zoysiagrass and St. Augustinegrass generally grow actively in summer and may benefit from fertilizer during that growing period. Cool-season grasses such as Kentucky bluegrass, tall fescue and perennial ryegrass often slow down in the heat, so pushing extra growth with nitrogen can add stress, especially during drought. Before choosing a summer lawn fertilizer, get a soil test and check local extension recommendations for your grass and region. The three numbers on a fertilizer bag show its percentages of nitrogen, phosphate and potash. Nitrogen supports leafy growth and green color, while phosphorus and potassium serve other important roles in plant health. More isn’t always better: choose a lawn feeding plan that addresses your soil’s needs, follows local fertilizer rules and avoids adding nutrients your yard already has. Getting the most from summer lawn care also means paying attention to fertilizer timing, application rates and watering. For an actively growing lawn that needs feeding, a slow-release nitrogen fertilizer can deliver nutrients gradually rather than all at once, but the label should guide the amount and application schedule. Measure your lawn before you start, set your spreader according to the product directions and apply evenly to help prevent streaks or fertilizer burn. Hold off on fertilizing grass that is dormant, drought-stressed or struggling through extreme heat, and avoid applications before heavy rain that could wash nutrients away. Follow the label’s watering directions after application, along with any local watering restrictions, and sweep stray granules off driveways and sidewalks back onto the lawn. Pair summer lawn fertilizer with mowing at the recommended height for your grass type and watering deeply as needed rather than giving the yard frequent light sprinkles. Those steady habits help support healthy roots and a lawn better prepared for summer foot traffic, from the front walk to the backyard.

Best Of FAQ

What do the three numbers on summer lawn fertilizer mean?

The three numbers show the percentages by weight of nitrogen, phosphate and potash, in that order. This is called the N-P-K ratio, and it gives you a straightforward way to compare fertilizer formulas.

What’s the difference between granular and liquid lawn fertilizers?

Granular fertilizers come as dry particles and are typically applied with a lawn spreader. Liquid fertilizers are applied with spraying equipment. Check the label for the application method and any mixing directions.

How does grass type affect a summer fertilizing schedule?

Warm-season grasses, such as bermudagrass and zoysiagrass, generally have their main growing season during warmer months. Cool-season grasses, such as tall fescue and Kentucky bluegrass, follow a different feeding calendar and may slow down in summer heat. Your local extension office can help you find a schedule for your grass and region.

Is lawn food the same thing as lawn fertilizer?

Lawn food is a common name for lawn fertilizer, rather than a separate product category. When comparing bags or bottles, look at the nutrient analysis and label directions instead of going by the name alone.

What information should I have before choosing a summer lawn fertilizer?

Start with your grass type, a recent soil test and a record of earlier fertilizer applications. A soil test can show soil pH and nutrient levels, giving you a starting point for choosing a formula. Local lawn-fertilizer rules may also shape your options and timing.
