By the Certified Lawn Care Specialists at Schwahn’s Lawns | Updated September 2025
Drawing from over 20 years of successfully maintaining Pinellas County lawns through hundreds of summer ban periods, this comprehensive guide provides everything you need to achieve beautiful, healthy lawns from June through September despite fertilizer restrictions and extreme heat stress.
🌞 The Critical Challenge: June-September in Pinellas County
Summer in Pinellas County presents the ultimate lawn care paradox: your grass experiences peak growing season and maximum stress simultaneously, all while you’re legally prohibited from using nitrogen and phosphorus fertilizers. From June 1 through September 30, successful lawn care requires completely different strategies than the rest of the year.
90°F+ temperatures + High humidity + No nitrogen/phosphorus = Your lawn’s most challenging 122 days
Summer lawn care during Florida’s fertilizer ban isn’t just about compliance—it’s about maintaining lawn health during the most stressful growing period using only legal alternatives. The homeowners who succeed understand that summer lawn care requires a complete strategic shift from spring and fall approaches.

Let certified experts handle your lawn’s most challenging season with guaranteed compliance and proven results.
Understanding the Summer Lawn Care Challenge
Before diving into solutions, it’s crucial to understand exactly why summer is so challenging for Pinellas County lawns and how the fertilizer ban affects your options.
Six Major Summer Challenges:
☀️ 1. Extreme Heat Stress
Daily temperatures exceeding 90°F put enormous stress on grass, increasing water and nutrient demands precisely when feeding options are restricted.
🚫 2. Fertilizer Ban
No nitrogen or phosphorus applications allowed June 1-September 30, eliminating traditional methods of maintaining green color and growth.
🐛 3. Peak Pest Season
Chinch bugs, grubs, and other lawn pests reach maximum activity during summer, attacking already stressed grass with devastating effects.
🍄 4. Disease Pressure
High humidity combined with heat creates ideal conditions for gray leaf spot and other fungal diseases that thrive in stressed lawns.
💧 5. Water Management
Sandy soils drain rapidly while grass needs more water, creating constant irrigation balancing act during afternoon thunderstorms.
🌀 6. Hurricane Season
Storm preparation, salt water flooding, and debris damage add emergency response requirements to already challenging summer care.
The Summer Lawn Care Success Formula
Successful summer lawn care during the ban period requires coordinating four critical components. Master these, and your lawn will not just survive—it will thrive.
The Four Pillars of Summer Lawn Success:
- Legal Fertilizer Alternatives – Maintain color and health without banned nutrients
- Pest and Disease Control – Protect stressed grass from opportunistic problems
- Irrigation Optimization – Deliver perfect moisture despite heat and storms
- Cultural Practice Excellence – Mowing, timing, and stress reduction

Legal Alternatives: Maintaining Color Without Banned Fertilizers
The #1 question homeowners ask: “How do I keep my lawn green without nitrogen?” The answer lies in understanding legal alternatives that work within the ordinance while delivering results.
Your Legal Summer Lawn Care Toolkit
✅ Allowed During Ban Period (June 1 – September 30):
- Iron sulfate and chelated iron: Maintains deep green color for 4-8 weeks
- Potassium sulfate: Enhances drought tolerance and disease resistance
- Micronutrient blends: Manganese, zinc, and other essential elements
- Organic matter: Compost, humic acid, and soil conditioners
- Beneficial microorganisms: Soil biology enhancement products
- pH adjusters: Lime and sulfur for soil pH optimization
❌ Prohibited During Ban Period – Avoid Fines:
- ANY nitrogen-containing fertilizers (N in N-P-K ratio)
- ANY phosphorus-containing fertilizers (P in N-P-K ratio)
- “Weed and feed” combination products (usually contain nitrogen)
- Violations = $50-$500 fines enforced by code compliance officers
Pest and Disease Control During Summer Stress
Stressed summer grass becomes highly vulnerable to pest infestations and disease outbreaks. Prevention and early detection are critical when your lawn is already fighting heat stress.
Primary Summer Threats
Chinch Bugs (Peak Season: June-August)
The #1 summer lawn destroyer in Pinellas County
- Tiny insects that suck plant juices and inject toxins
- Damage appears as irregular yellow patches turning brown
- Often mistaken for drought stress or fertilizer deficiency
- Can devastate entire lawns within 2-3 weeks if untreated
- Professional treatment often necessary for control

Gray Leaf Spot (Peak Season: June-September)
The summer disease that loves stressed St. Augustine grass
- Small gray spots with dark borders on grass blades
- Thrives in hot, humid conditions with frequent rainfall
- Spreads rapidly on stressed, overly watered lawns
- Can cause severe thinning if left untreated
- Requires fungicide applications for control

Irrigation: The Make-or-Break Summer Factor
More summer lawns fail from improper watering than any other cause. Getting irrigation right during June-September is absolutely critical for survival.
The Perfect Summer Watering Schedule
| Factor | Optimal Summer Approach | Why It Matters |
|---|---|---|
| Timing | 4-8 AM only | Minimizes disease, maximizes absorption |
| Frequency | 3-4 times weekly | Balances drought stress and overwatering |
| Duration | 45-60 min per zone | Reaches 6-8 inch root depth in sandy soil |
| Total Amount | 1-1.5 inches weekly | Includes rainfall in weekly total |
| Rain Adjustment | Skip if 0.5″+ rain | Prevents disease from overwatering |
Critical Summer Mowing Guidelines
Summer Mowing Best Practices:
- Raise mowing height to maximum: Higher grass = better heat tolerance
- St. Augustine: 4 inches (never below 3.5 inches)
- Bahia: 4 inches during heat stress
- Zoysia: 2.5-3 inches (high end of range)
- Mow weekly without exception: Consistent height prevents stress
- Never remove more than 1/3 blade height: Severe shock to stressed grass
- Mow when completely dry: Early morning after dew evaporates
- Keep blades sharp: Clean cuts vs. torn, disease-prone edges
- Vary mowing pattern: Prevents ruts and compaction
Hurricane Preparation and Recovery
Summer lawn care in Pinellas County must include hurricane preparedness and rapid post-storm response to prevent permanent damage.
Pre-Storm Preparation (72 Hours Before):
- Clear all drainage systems and remove debris
- Document lawn condition with photographs
- Secure or store all lawn equipment and decorations
- Apply anti-transpirant to protect plants from salt
- Lower irrigation system settings before evacuation
