Florida summers are no joke—heat, humidity and heavy rains can take a toll on even the healthiest lawns. Whether you're dealing with St. Augustine, zoysia or any other warm season grass, your yard needs extra TLC to stay in tip-top shape through the hottest months of the year.
Let’s dive into the smart strategies that keep Florida lawns looking their best all summer long.
Summer Lawn Care Tips
Quick Look at What’s Ahead:
- Mow Smarter, Not Harder
- Feed Wisely: Balanced Summer Fertilization
- Water with Precision: Less is More
- Be Cautious with Weed Control
- Keep an Eye Out for Sneaky Summer Bugs
- Prepare for Storms
- Watch for Lawn Diseases
1. Mow Smarter, Not Harder
Keeping your grass trimmed during a Florida summer requires more than just cranking up the mower. The key is maintaining the right height for your grass type to avoid stress and promote healthy growth.
Recommended Mowing Heights:
- Bermuda: 0.5–1.5 inches
- Centipede: 1.5–2.0 inches
- St. Augustine: 2–4 inches
- Zoysia: 0.5–2 inches (based on blade type)
Quick Tips:
- Make sure your mower blades are sharp. Dull mower blades will rip the grass damaging the grass.
- Never remove more than one-third of the blade at once.
- If your grass gets too tall while you're away, raise your mower height and then lower it gradually over several mowings spaced 3–5 days apart.
- Leave grass clippings on the lawn to decompose naturally—they return valuable nutrients to the soil.
- Shaded areas should be mowed at a higher height, which allows for less frequent mowing—about once per week. For lawns mowed at 2.5 inches, mowing every five days, or twice a week, is recommended.
2. Feed Wisely: Balanced Summer Fertilization
Hot weather and heavy rains make fertilizing a bit tricky. Overdoing it can burn your lawn, while underfeeding leads to weak, nutrient-starved turf.
What We Recommend:
- Lawnifi® Summer Fertilizer Box – A liquid fertilizer system featuring Maintain and Recover formulations for steady nourishment without stress.
Why It Works:
- Easy hose-end application
- Fast-acting and efficient
- Promotes deep root growth and stress resilience
Pro Tips:
- Apply fertilizers in early summer (April–June).
- Avoid fertilizing during peak rainy months to prevent nutrient runoff.
- Consider doing a soil test to determine exactly what your lawn needs—Florida soils often already contain high phosphorus levels.
Always clean up fertilizer from driveways and sidewalks to prevent stormwater contamination. A deflector shield or liquid fertilizer like Lawnifi can help minimize waste and runoff.
3. Water with Precision: Less is More
Overwatering is one of the top causes of lawn problems during Florida summers. Shallow roots and increased disease risk are just the beginning.
Train Your Grass to Thrive:
Let your lawn signal when it’s thirsty:
- Folded or curled leaves
- A dull, bluish-gray hue
- Footprints that linger
Your Watering Goals:
- 1 inch of water per week, including rainfall
- Water early in the morning (before 10 AM)
- Deep watering 1–2 times per week encourages stronger roots
Bonus Tips:
- Use a rain gauge or perform a quick irrigation audit to check your output.
- Install a rain sensor to prevent irrigating when not needed.
- Most Florida counties limit irrigation to twice a week—stay in compliance.
- Install rain barrels to collect and reuse stormwater efficiently.
4. Be Cautious with Weed Control
Hot temps and herbicides don’t always mix well. Blanket applications in the middle of a Florida summer can lead to unsightly browning.
Smart Weed Control Strategies:
- Spot-treat weeds or hand-pull when possible
- Wait until fall for full-yard treatments
- Always follow product labels carefully
Summer Weed Control Products:
- Broadleaf Weed Control: SpeedZone Broadleaf Herbicide for Turf
- Grassy Weed Control: Drive XLR8
- Weed Control for St. Augustine & Centipede Lawns: Hi-Yield Atrazine Weed Killer
5. Keep an Eye Out for Sneaky Summer Bugs
Summer bugs are like party crashers—they show up uninvited and do damage fast. The big ones to watch out for:
- Grubs – ruin roots, cause patches
- Chinch bugs – suck the greenness out of your grass and leave drought-like patches
- Sod webworms – munch the blades
- Mole crickets – create tunnels and damage roots
- Spittlebugs – yes, they spit foam… gross, right?
If you’re seeing weird damage and not sure what’s up, try a “tug test”—gently pull on the grass. If it lifts up easily, you’ve probably got grubs.
Chinch Bugs & Sod Webworms
Chinch Bugs:
Thrive in hot, dry conditions and especially target St. Augustine lawns. These tiny pests feed at the base of grass blades, draining sap and injecting toxins that cause browning.
- Solution: Bifenthrin (Bifen XTS)
Sod Webworms:
These caterpillars are most active at night. They feed on the blades and leave behind irregular brown patches. Look for tiny moths fluttering over your lawn at dusk as a sign of their presence.
- Solution: Spinosad (Natural Guard Spinosad)
6. Prepare for Storms
Florida’s hurricane season (June–November) brings heavy rains, wind and potential flooding. Safeguard your lawn and landscape by:
- Improving drainage and addressing low spots
- Securing loose items like lawn furniture and decor
- Aerating your lawn to improve water absorption
7. Watch for Lawn Diseases
Warm, humid conditions also invite fungal diseases, especially in overwatered, overfertilized or poorly drained areas.
Common Summer Lawn Diseases:
Gray Leaf Spot: Appears as small, oval spots with gray centers and dark borders.
- Solution: Azoxystrobin (Heritage G).
- Watch for gray leaf spot on St. Augustine grass, especially in shaded areas. Avoid overwatering and excessive fertilizer applications, as these can worsen the problem.
Root Rot: Causes thinning and yellowing due to soggy conditions and poor drainage.
- Solution: Chemical treatments are rarely effective; however, fungicides, including Azoxystrobin (Heritage G), can help prevent this disease.
Be sure to occasionally rotate any fungicides to prevent diseases from developing resistance. Prevent problems by avoiding overwatering, improving airflow and treating promptly at the first sign of disease. Also, be cautious with nitrogen—over-fertilized lawns, especially those high in nitrogen, are more susceptible to disease, as nitrogen can help it spread.
Summer lawn care in Florida is all about balance—enough water, not too much fertilizer and timely maintenance. With these strategies, your lawn can handle the heat and stay beautiful all season long.
Taking care of your lawn in the summer doesn’t have to be overwhelming—it just takes a bit of planning and the right approach. With these tips, you’ll give your grass exactly what it needs to power through the heat, bounce back from dry spells and keep looking great all season long. Your future self (and your yard) will thank you.
