About Lawn Care in Highlands County, Florida
High Difficulty for Central Florida Lawns
Highlands County presents a challenging environment with a lawn difficulty score of 14.7, trailing both the state and national averages. Located in hardiness zone 9b, this region demands more effort and resources than 85% of the country to maintain a lush lawn. Growers must adapt to high heat and very specific soil chemistry.
Extended Seasons and Intense Heat
With 126 extreme heat days, Highlands is much hotter than the state average of 92. The region receives 52.8 inches of rain annually, which is near the Florida average, but the 8,448 growing degree days indicate a very long growing season. This combination requires careful irrigation management to prevent turf from scorching during the peak summer months.
Correcting Highly Acidic Ridge Soils
Highlands County features some of the state's most acidic soil with a pH of 4.61, far lower than the ideal 6.0-7.0 range. The soil is 76.7% sand and only 2.0% clay, providing very little natural nutrient retention. Aggressive liming and the addition of organic matter are essential steps to stabilize the soil foundation.
Navigating 100% Severe Drought Coverage
The entire county is currently experiencing severe drought, having spent 34 weeks in drought conditions over the past year. Without proper intervention, these conditions can lead to permanent turf loss in sandy areas. Prioritizing water conservation through mulch-mowing and morning-only irrigation is vital for preserving your lawn.
Starting Your Highlands County Lawn
St. Augustine grass remains a popular choice for zone 9b due to its heat tolerance, though Bahia is better for low-water sites. Plan your major lawn work for after February 1, which marks the typical end of the spring frost risk. This early start gives your turf time to mature before the 126 days of 90-degree heat arrive.

Seasonal Lawn Care Checklist
Spring
- Apply pre-emergent herbicide when soil reaches 55F
- 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
- Service mower and sharpen blades
- Plan spring soil amendments based on fall test
- Overseed with ryegrass for winter color

Common Lawn Problems in Highlands County
Excess Moisture & Fungal Disease
High annual rainfall (53 inches) increases risk of fungal diseases like brown patch and dollar spot. Ensure good drainage and avoid overwatering.
Acidic Soil

Persistent Drought Conditions
Highlands County experienced drought conditions for 34 of the past 52 weeks. Prioritize water-efficient grasses and consider reducing lawn area.
