A Guide to Cool Season Grass Varieties

Maintaining a beautiful and lush lawn requires selecting the right grass variety that thrives in your specific climate and conditions. For those in regions with cooler temperatures, cool season grasses are the answer. These grasses thrive in the milder months and provide a vibrant green carpet that can withstand the chill. In this comprehensive guide, we'll explore some of the popular cool season grass varieties, highlighting their features, benefits, and best practices for their care.

Understanding Cool Season Grasses

Cool Season Grass Care Tips

Soil Preparation: Ensure proper soil preparation before seeding or laying sod. Well-draining soil with good organic content promotes healthy grass growth.
Mowing Height: Maintain a mowing height suitable for your chosen grass variety. Generally, cool season grasses are best kept between 2.5 to 4 inches in height.
Regular Watering: While cool season grasses are adapted to cooler weather, they still require consistent watering, especially during drier periods.
