How Long for Tall Fescue Grass to Grow?

Answer

Tall fescue, also known as Festuca arundinacea, contributes to the maintenance of a green lawn throughout the year by flourishing during the dormant season in plant hardiness zones 3 through 8 according to the United States Department of Agriculture. The University of California states that tall fescue is a grass that thrives throughout the chilly season and does best in locations that get full sun or light shade. Because of how quickly it grows, it needs to be mowed quite frequently. Additionally, it germinates very quickly, which enables you to overseed your lawn or put tall fescue grass seed in new places without having to wait an excessive amount of time to make use of them.

How to Seed Tall Fescue

Tall fescue grows at varying rates depending on the temperature. It may take the tall fescue grass seed longer to germinate in the spring than it does in the fall because the soil temperature needs to be between 50 and 65 degrees Fahrenheit for it to germinate successfully. If you plant the seed in the spring, when the soil is still cold, the grass may take longer to germinate. When air temperatures range from 60 to 75 degrees, it grows at a rapid rate. When the temperature starts to drop in the autumn, fescue will begin to grow at a faster rate than it does during the hot summer months.

According to Seedland, the appropriate amount of seed to apply for planting should be between 5 and 10 pounds per 1000 square feet (or between 220 and 435 pounds sown per acre).

Tall Fescue Germination Time

The time it takes for tall fescue to germinate after being sown in the autumn normally ranges from four to fourteen days. The rate at which seeds germinate is determined by a number of variables, including the pH of the soil, the temperature, and the frequency with which they are watered. Although it thrives in soil with a pH in the range of 5.8 to 6.5, tall fescue may survive in soil with a pH in the range of 4.7 to 8.5. The tall fescue grass seeds need to be watered every day to keep the soil wet and speed up the process of germination for the tall fescue grass seeds.

How to Mow Tall Fescue

Do not rush to get the lawn mower as soon as you see the first few teeny-tiny green sprigs appearing on the grass. It is recommended that you let the seedlings of tall fescue between two and four weeks to develop to a height at which they may be mowed without causing any damage to the plant. If you wait until the grass is at least 2 and a half inches tall, you may be confident that the roots have established themselves firmly enough to withstand being cut.

Each time you mow, including the very first time, you should cut down roughly a third of the height of the blades. Remove one inch of height, for instance, from grass that is three inches tall. When the temperature is lower, tall fescue grows more fast, so you should plan to mow it every five to seven days. During the warmer months of spring and autumn, you should mow your tall fescue lawn more regularly. However, during the hot summer months, you should allow the tall fescue grow a little higher — around 4 inches tall, according to the University of Arkansas — between mowings.

Proper Tall Fescue Care

It is vital to mow tall fescue at the appropriate time in order to provide effective management and care for tall fescue. Tall fescue, when not tended to, may reach a height of up to 48 inches in only one year. It’s possible that this won’t be an issue in the middle of your lawn, where it’s easiest to mow, but if you don’t edge or trim the grass in other places, such around trees or your mailbox, it may start to appear out of control very fast.

Even tall grass requires just a third of its height chopped off at any one moment in order to preserve its health; wait three to four days and then trim off another third of the grass’s height, repeating this process until the grass is at the ideal height.
