If you have done any traveling across the united states, you may have noticed that not everyone’s grass is the same. I grew up in a cool season area and when I spent some time down south in Texas and Florida, I was blown away that people would choose some of these thicker, more rough types of grass instead of the softer, fescue blends I was used to. It wasn’t until years later that I realized that there are certain types of grasses that are best suited for particular environments. In this post, we will go over the main types of cool season and warm season grasses, the three different zones, and where these zones are generally located so you know which type of grass is best for your lawn.
Cool Season Grasses
Cool-season grasses thrive in regions with cold winters and mild summers. They grow best in spring and fall when temperatures range between 60-75°F. These grasses are most common in northern regions of the U.S. Popular cool-season grasses include Kentucky bluegrass, tall fescue, fine fescue, and perennial ryegrass. Each type has its pros and cons, so it’s common to see blends that combine the benefits of each. If you live in a colder climate, these grasses will give you a lush, green lawn most of the year but may go dormant during the hottest summer months.
Warm Season Grasses
In the southern part of the U.S., where summers are scorching and winters are mild, warm-season grasses thrive. These grasses grow best in hot weather, typically when temperatures are above 80°F, and they go dormant during cooler months. The most common warm-season grasses are Bermuda, zoysia, centipede, and St. Augustine. While these grasses tend to be resilient and thick, they often turn brown and go dormant in the winter months.
Transition Zone
If you live in an area where summers are too hot for cool-season grasses but winters are too cold for warm-season varieties, you’re in the transition zone. This can be a bit tricky because you’re dealing with both extremes—heat and cold. In the transition zone, a mix of cool- and warm-season grasses usually works best. You might also find seed blends specifically designed for your region. Watering heavily during summer can help maintain your cool-season grass’s color when temperatures soar.
Some of the best options for the transition zone include tall fescue, zoysia, hybrid Bermuda, or overseeding with ryegrass. Tall fescue is one of the most heat-tolerant cool-season grasses and can survive summer better than others. Zoysia, a warm-season grass, handles cooler temperatures better than most warm-season varieties. Hybrid Bermuda is essentially a Bermuda grass adapted to withstand cooler weather. Overseeding with ryegrass in the fall is another option to keep your lawn green during winter.
Final Thoughts
I hope this helps answer the question of what type of grass is best for your lawn. If you’re still unsure, the best step is to visit your local agricultural extension office—they can guide you in the right direction. Once you’ve found your perfect grass, don’t wait—go ahead and dance on the lawn!
