About Lawn Care in Highland County, Virginia
High Altitude Lawn Challenges
Highland County presents a unique challenge with a lawn difficulty score of 48.2, falling below the national and state averages. Located in the cooler Hardiness Zone 6a, you face a shorter growing season and lower temperatures than most of Virginia. Your maintenance routine must adapt to these mountain conditions to be successful.
Cool Summers and Ample Rain
With only one extreme heat day per year, heat stress is rarely a concern for your turf. However, you only have 2276 growing degree days, which is nearly half the count of some coastal Virginia counties. This means grass grows slower and takes longer to recover from damage or heavy foot traffic.
Working with Acidic Mountain Soil
The soil pH in Highland is 4.90, which is very acidic and requires significant intervention to support a traditional lawn. Your soil composition has 16.2% clay and 36.5% sand, which can lead to drainage issues in low-lying areas. Regular aeration and heavy liming are necessary to create a hospitable environment for grass.
Coping with Prolonged Drought
The county has faced 33 weeks of drought over the past year, making it one of the more drought-prone areas in the region. Currently, 100% of the county is abnormally dry, which is particularly tough on lawns growing in thin mountain soils. Focus on keeping your lawn taller when mowing to shade the soil and retain every drop of moisture.
Timing the Short Growing Season
In Zone 6a, cool-season grasses like Fine Fescue and Kentucky Bluegrass are your best options for survival. You have a narrow window for seeding between the last spring frost on May 12 and the first fall frost on October 5. Early fall is the most reliable time to plant, as it avoids the potential for late spring freezes.

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
- Service mower and sharpen blades
- Plan spring soil amendments based on fall test
- Keep lawn clear of debris
