How Long for Tall Fescue Grass to Grow?
- Tall fescue grass grows fastest during spring and fall. This is typical of cool-season grasses, according to the Virginia Cooperative Extension.
- Tall fescue turfgrass grows between 1/2 and 1 inch every five days, according to Texas A&M University. Growth occurs in the low end of this range during the summer.
- The original tall fescue grass that grows in clumps rather than as a turfgrass grows even faster. Starting at a height of 2 or 3 inches, it will reach the 8 to 10 inch mark within three weeks during spring or five weeks during summer, according to the West Virginia University Extension Service.
