Abundant Rainfall Fuels Douglas Lawns

Balanced Texture and Ideal pH
The soil pH of 6.34 is optimal for turf, ensuring that grass can easily access essential nutrients. A mixture of 24.9% clay and 20.5% sand provides a texture that balances moisture retention with essential drainage. These naturally fertile conditions minimize the need for heavy soil remediation.

The higher annual rainfall provides a natural buffer that helps lawns recover quickly from dry spells. Practicing smart irrigation during the 43 heat days will keep the turf vibrant all summer.
Establish Your Douglas Lawn in April
Tall fescue is a local favorite for its deep roots and durability in the Zone 6b transition zone. Seeding should begin after the last frost on April 15 to ensure the grass is strong before summer. Your lawn's growing window remains open until the first fall frost hits around October 22.
