About Lawn Care in Hendry County, Florida
Tough Turf Conditions in Hendry County
Maintaining a lawn in Hendry County is a major challenge, reflected in a low difficulty score of 14.1 compared to the national median of 50.0. Situated in hardiness zone 10a, this area is even more demanding than the Florida state average of 19.2. Homeowners here must navigate extreme heat and tropical pressures that most of the country never faces.
Intense Heat Drives Constant Mowing
Hendry endures 130 extreme heat days per year, crushing the state average of 92 days. This heat, combined with 8,810 growing degree days, keeps grass in a state of rapid growth throughout most of the year. While 52.6 inches of annual rain is plentiful, the relentless sun necessitates a strict irrigation and mowing schedule.
Acidic Sands Demand Heavy Soil Prep
The soil foundation is highly acidic with a pH of 4.90, falling far below the 6.0 to 7.0 ideal range for most turf. With a sand content of 78.9% and only 2.0% clay, nutrients wash away quickly after heavy rains. Homeowners usually need significant lime applications and organic amendments to help the ground hold onto moisture and fertilizer.
Battling Severe Year-Round Drought
Currently, 100% of Hendry County is under severe drought conditions, and the area has spent 39 weeks in drought over the past year. This persistent dry spell makes water conservation vital for lawn survival. Deep, infrequent watering early in the morning is the most effective way to protect your grass during these dry cycles.
Planting for Success in Zone 10a
Heat-loving species like St. Augustine and Bermuda grass are the top choices for Hendry's tropical climate. With the last spring frost typically occurring by January 27, the window for seeding or laying sod is wide open early in the year. Start your lawn projects in late winter to establish strong roots before the peak summer heat arrives.

- Begin mowing when grass reaches 3 inches
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Raise mowing height to reduce heat stress
- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
Fall
- Overseed warm-season lawns if thinning
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
- Apply pre-emergent for winter weeds
