Cooler Summers and Manageable Growth
With only 6 extreme heat days per year compared to the state average of 28, Pulaski lawns face very little heat stress. The 40.0 inches of annual precipitation provides a steady supply of moisture for the 3,070 growing degree days.
Clay-Rich Soils with Drainage Needs

Navigating Moderate Seasonal Dryness
The county experienced 26 weeks in drought last year, though current conditions remain only 'abnormally dry.' Because the summers are cooler, lawns here recover faster from dry spells than those in the hotter eastern parts of Virginia.
Seeding for Success in the Mountains
Kentucky Bluegrass and Fine Fescue thrive in these cooler conditions, especially with the April 25 to October 17 growing season. Planting should occur shortly after the spring frost to take advantage of the mild summer temperatures.
