What Is Warm Season Grass and How to Cultivate?
What Is Warm Season Grass?
Warm season grass refers to a category of grasses that originally come from tropical regions and thrive in hot temperatures.
They are best suited for growth when temperatures range from 75-90°F and typically experience the most growth during the summer months.
In late fall and winter, warm season grasses go dormant and turn brown, remaining in this state until warmer weather returns in the spring.
Some examples of major warm season grasses include bahia grass, bermuda grass, centipede grass, St.
Augustine grass, and zoysia grass.
These grasses have different characteristics such as color, texture, heat tolerance, and drought resistance.
Warm season grasses are commonly found in the Gulf States, Southern California, and throughout the South and Transition Zone.
In the Transition Zone, where both cool and warm season grasses are found, popular warm season varieties include bermuda grass, centipede grass, and zoysia grass.

Did You Know?
1. Warm-season grasses thrive in regions with longer periods of hot weather and are specifically adapted to warm climates, such as the Southern United States, Africa, and Australia.
2. Unlike cool-season grasses that grow actively during spring and fall, warm-season grasses experience peak growth during the summer months when temperatures are consistently high.
3. Bermuda grass, a popular warm-season grass, was introduced into the United States from Africa during the colonial era and quickly spread throughout the South due to its ability to tolerate both heat and drought.
4. Zoysia grass, another type of warm-season grass, is known for its dense and durable growth, making it ideal for heavy foot traffic areas like golf courses and sports fields.
5. While warm-season grasses typically require less water than their cool-season counterparts, they often enter a dormancy stage during colder months, resulting in a brown and straw-like appearance until warmer temperatures return.
Characteristics And Origin Of Warm-Season Grasses
Warm-season grasses are a diverse group of grasses that originate in tropical regions. These grasses are suited to hot temperatures and thrive in environments where temperatures range from 75-90°F. They experience most of their growth during the summer months when temperatures are at their peak. However, one distinctive characteristic of warm-season grasses is their tendency to go dormant and turn brown in late fall and winter when temperatures drop. They will green up again once warmer weather returns in the spring.

Cool-Season Grasses And Their Uses
Cool-season grasses have their own unique set of characteristics and uses. Fescue, a type of cool-season grass, is well-known for its ability to withstand foot traffic and adapt to fluctuating temperatures. Creeping Red Fescue, a fine fescue variety, is often used in shady areas due to its slow growth rate and tolerance of low light conditions. Perennial Ryegrass is a cool-season grass that blends well with other grass types and can handle high traffic, making it a popular choice for sports fields and high-use areas.
- Cool-season grasses have unique characteristics
- Fescue is known for withstanding foot traffic and fluctuating temperatures
- Creeping Red Fescue is ideal for shady areas with slow growth and low light tolerance

Choosing The Right Seed And Ensuring Quality
When establishing a new lawn from seed, it is crucial to use clean seed to avoid weed contamination. Using certified seed is highly recommended to ensure the highest quality and viability. Certified seed indicates that the seed has undergone testing and met specific standards regarding purity and germination. By choosing certified seed, homeowners can have greater confidence in the establishment and long-term success of their lawn.
Furthermore, it is advisable to avoid seed containing annual ryegrass. This grass type can quickly grow and dominate a lawn, leading to an imbalance in grass species and potentially causing issues in the lawn’s overall appearance and health. Therefore, careful consideration of the seed type is essential to achieve the desired results and maintain a healthy and attractive lawn.
