Data Story
About Lawn Care in Logan County, Oklahoma
Logan County’s Tough Turf Landscape
Logan County presents a significant challenge with a lawn difficulty score of 41.4, which is lower than both the state and national averages. Situated in Hardiness Zone 7b, the local climate and soil conditions require more intensive management than neighboring Lincoln County. Success here depends on a proactive approach to soil health and irrigation.
High Heat Demands Strict Watering Schedules
Logan County faces 79 extreme heat days annually, exceeding the Oklahoma average of 76 days and putting turf under intense thermal stress. The 35.0 inches of annual precipitation is adequate, but it often evaporates quickly during the high-degree-day summer months. Careful monitoring of your 5113 growing degree days will help you time your mowing and fertilization cycles effectively.
Managing Sandy Soil and High Moisture
The soil pH of 6.02 is ideal for most turfgrasses, but the high sand content of 45.7% means nutrients can leach away quickly. While specific drainage data is limited, the sandy texture suggests you may need to fertilize more frequently with slow-release products. Adding organic matter will help stabilize the soil and improve its ability to hold onto the moisture your lawn needs.
Battling Prolonged Drought in Logan
With 37 weeks in drought over the past year, Logan County is one of the more water-stressed regions in the state. Currently, 100% of the county is in abnormally dry conditions, though severe drought levels remain low for now. To conserve water, prioritize mulching around lawn edges and maintain a higher mowing height to shade the soil surface.
Establishment Timing for Zone 7b
Bermudagrass is the gold standard for Logan County because of its excellent heat tolerance and ability to thrive in sandy soils. You should wait until after the typical last frost on April 10th to start your spring planting. The growing season remains active until the first fall frost, which usually hits around November 1st, giving you time for late-season repairs.

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
- Mow at recommended height weekly
- 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
