Three Types of Grass That Grow in Two Weeks or Less

Fast growth and quick germination times are unique adaptions found only within a small number of lawn grass varieties. The vast majority of grasses take between two to three weeks to germinate with a small minority breaking the two week barrier. Lawn grasses are typically planted in the early spring, mid-summer or early fall depending on whether they are a warm or cool season variety.

Perennial Ryegrass

Perennial ryegrass is a cool-season grass preferring moist, temperate environments with relatively moderate temperature fluctuations. When planted in the early fall, in ideal conditions, perennial ryegrass germinates in five to seven days. The fast growth rate of ryegrass makes this variety desirable as a temporary ground cover during the winter months in southern states. Perennial ryegrass has a shallow root system, making it vulnerable to periods of prolonged drought.

Tall Fescue

Tall fescue is a bunching, cool-season grass that grows rapidly during the spring and fall months in the northern United States. When seeds are planted in the early spring or fall they typically germinate within seven to ten days. Drought- and shade-tolerant, tall fescue grass is successfully grown without irrigation and in the partial shade found under trees. This grass has a high degree of resistance to foot-traffic and disease, making it ideal for high-use lawn areas.


Bermuda is a popular warm-season grass found in the southern United States that produces a dense, light green turf. Like all warm-season grasses, Bermuda grows fastest in the direct sunlight and hot temperatures of the summer months. When planted during mid-summer, Bermuda grass can germinate within five to seven days. Bermuda grass tolerates cold temperatures and high amounts of foot traffic but suffers in shady, dry environments.
