Top 6 Summer Lawn Care Tips You Need to Know
These proven summer lawn care tips will help you keep your grass green, healthy, and weed-free all season long.
When summer hits, your lawn faces its toughest test. Long days, scorching sun, and heavy foot traffic can take even the healthiest grass from lush green to thin and brown in weeks. The truth is, most warm-season lawns don’t decline because of one big mistake—they suffer from a series of small, avoidable issues like poor mowing habits, weak watering routines, or skipping fertilizer altogether.
The good news? By following these summer lawn care tips, you can protect your investment and enjoy a thick, vibrant lawn all season long. Whether you’re caring for Bermuda, Zoysia, St. Augustine, or Centipedegrass, these strategies will help you keep your grass healthy, resilient, and ready to show off.
Tip # | Focus Area | Key Actions | Benefits | Extra Pro Tips |
1 | Watering | Apply ~1.25″ water/week (incl. rainfall); use catch cans to measure output; water 4–5 days/week for absorption. | Prevents drought stress & weed growth; encourages deep roots. | Adjust schedule for weather; check sprinkler types for run times. |
2 | Mowing | Follow 1/3 rule; use proper height per grass type; mow frequently enough to avoid scalping. | Promotes thick, healthy turf; reduces weeds. | Keep mower blades sharp; adjust height seasonally. |
3 | Fertilization | Apply correct nitrogen rates for each grass type; use 1-1 or 2-1 N:K ratio; treat iron deficiencies if needed. | Boosts summer growth, color, and resilience. | Use formula (100 ÷ first number on bag) to calculate application rate. |
4 | Weed Control | Identify weeds; match herbicide to weed type; apply during active growth. | Keeps lawn uniform; reduces competition for water/nutrients. | Celsius + Certainty for sedges; Change-Up + Celero for Virginia buttonweed. |
5 | Bare Spot Recovery | Fix root cause; topdress small areas with sand; fertilize & water; for large areas, sprig or sod. | Restores turf coverage; prevents erosion & weeds. | Mow frequently to encourage spreading; stagger sod seams for coverage. |
6 | Wear & Tear Prevention | Rotate play areas; protect recovering zones; limit repeated traffic. | Extends turf life; prevents compaction & damage. | St. Augustine & Centipedegrass are most sensitive—protect these more. |
1. Water Your Lawn Like a Pro
Water is life for your lawn—but too much or too little can spell trouble. Overwatering leaves soil soggy, creating a breeding ground for weeds like kyllinga, nutsedge, and doveweed. Underwatering, on the other hand, weakens roots and leaves your grass vulnerable to drought stress and pests.
For most warm-season lawns, the sweet spot is about 1.25 inches of water per week, including rainfall. This amount keeps roots strong without wasting water.
How to Measure Water Output
Don’t guess—test your irrigation system. Here’s how:
- Place catch cans (like coffee mugs or glass cups) around your lawn’s irrigation zone.
- Run your system for 15 minutes.
- Measure the water collected. If you get about 0.25 inches in that time, you’ll need to run that zone for about an hour each week to hit 1 inch.
- Divide watering into 4–5 sessions per week for better absorption and less runoff.
General Guidelines by Sprinkler Type:
- Spray heads: 12–13 minutes per day, 5 days a week
- Rotors: 25 minutes per day, 5 days a week
- MP rotators: Similar to rotors—25 minutes per day, 5 days a week
For consistent results, consider professional sprinkler maintenance or irrigation repair to ensure even coverage.
2. Master the Art of Mowing
Mowing may seem simple, but doing it wrong can set your lawn back for weeks. Cutting too short stresses grass and invites weeds; waiting too long causes scalping and thatch buildup.
Follow the 1/3 rule—never remove more than one-third of the blade height at a time. This keeps the lawn healthier, supports photosynthesis, and reduces stress.
Recommended Mowing Heights:
- Bermuda & Zoysia: 0.75–1 inch (reel mower) or 1–2 inches (rotary mower). Mow every 2–3 days at low heights, weekly at higher heights.
- Centipede: 0.75–1 inch (reel) or 1–2 inches (rotary). Never let it exceed 2.5 inches.
- St. Augustine: 2.5–4 inches. Mow weekly for best results.
Hiring a professional lawn mowing service ensures precision cuts, healthy growth, and consistent curb appeal.
3. Feed Your Lawn for Peak Growth
Summer is prime time for growth in warm-season grasses, and nitrogen is the fuel that powers it. The right fertilization schedule will keep your lawn thick, green, and able to resist weeds and pests.
Fertilization Guidelines by Grass Type:
- Bermuda: 0.5–1 lb nitrogen per 1,000 sq. ft. monthly from May to August (3–6 lbs total for the season).
- Centipede: 0.5–1 lb in mid-May, followed by 0.5 lbs in June and July (1–2 lbs total per year).
- St. Augustine: 0.5–1 lb in May, 1 lb in June, 0.5 lb in July.
- Zoysia: 0.5–1 lb about three weeks after green-up, then again in June/July and August (3 lbs total per year).
How to Calculate Application Rate:
Divide 100 by the first number in the fertilizer ratio to get the pounds needed per 1,000 sq. ft. for 1 lb of nitrogen. Example: 22-0-12 fertilizer → 100 ÷ 22 = 4.5 lbs per 1,000 sq. ft.
To maximize results, invest in professional fertilization services as part of your lawn treatment plan.
4. Stay Ahead of Summer Weeds
Hot, humid weather is weed paradise. Sedges, Virginia buttonweed, and doveweed thrive if your lawn care routine slips.
Steps to Beat Summer Weeds:
- Identify the weed—different weeds need different treatments.
- Match herbicide to weed type for maximum effectiveness.
- Apply when weeds are actively growing, and follow label directions carefully.
Recommended Combinations:
- Celsius + Certainty: Controls a broad range of weeds, including sedges.
- Change-Up + Celero: Targets Virginia buttonweed, chamberbitter, and nutsedge.
For best results, let the pros handle it with weed control services tailored to your lawn.
5. Repair Bare Spots Quickly
Bare patches happen—from pests to disease to foot traffic—but leaving them alone invites weeds and erosion.
For Small Areas:
- Fix the cause (pests, weeds, irrigation issues).
- Mow and lightly rake to loosen soil.
- Topdress with ½ inch of clean, dry sand.
- Fertilize and water every 2–3 days.
- Mow every few days to encourage lateral growth.
For Large Areas:
- Sprigging: Plant small grass pieces directly into the soil. Cost-effective but slower to fill in.
- Sodding: Instant coverage but more expensive. Lay sod like bricks, water immediately, and avoid traffic for several weeks.
If you want to smooth and restore your turf, topdressing lawn leveling can make a big difference.
6. Protect Against Summer Wear and Tear
Summer is when your lawn gets the most use—kids playing, pets running, cookouts with friends. Constant wear can damage even the toughest grass.
Protect Your Lawn By:
- Rotating play areas.
- Keeping pets off recovering zones.
- Avoiding repeated traffic in one area.
Note: St. Augustine and Centipedegrass are especially sensitive to foot traffic—protect them to avoid damage.
