How to Grow and Care for Tall Fescue Grass

Tall fescue is a perennial cool-weather turf grass that stands out because of its growth habit. The leaves are wide blades with a dark green color that is maintained even in winter. The ribbed blades are very coarse to the touch, with topsides that are shiny. As the newest leaf blades emerge, they appear in a rolled-up form.

Tall fescue is known for its fast, upright, clumping growth habit that is sometimes known as "bunchgrass." Although tall fescue grass possesses small rhizomes, it spreads mostly by seed distribution rather than by creeping. When it dominates a mixed-grass lawn, it may appear as isolated, awkward-looking clumps rather than in a uniform mat like other grasses.

Tall fescue is a tough grass that is a good choice for play areas, though it may require reseeding when bare spots occur. The cultivars used for lawn seed are usually dwarf varieties.

Tall Fescue Grass Care

Tall fescue grass is a cool-season grass. The best time to plant it is during peak growth periods in the fall and spring. Because this grass tends to bunch, it can benefit from periodic overseeding to keep the density but avoid a clumpy appearance.

This type of grass is drought tolerant and does not require a lot of fertilization. The roots develop a very deep system, reaching between 2 and 3 feet. Because of this, tall fescue survives well without regular watering and is a good eco-friendly choice where water is scarce.

Wait until a new lawn is well established, with blades 4 inches or more in length, before mowing for the first time. If the lawn is entirely tall fescue rather than a mixture, it is often recommenced to keep your mower set at its maximum blade height.

Light

Tall fescue grass can grow in full sun to part shade. These grasses are shade tolerant and grow well in areas where it's too hot for cool grasses but too cold in the winter for warm-season grasses.

Soil

These grasses are adaptable to many types of soil. The deep roots can find nutrients and moisture in almost any soil type.

Water

Weekly watering of 1 to 1 3/4 inches of water is beneficial but not essential. When watering, the goal should be to wet the soil to a depth of 4 to 6 inches. The long roots make tall fescue grass quite drought-resistant.

Temperature and Humidity

Tall fescue has good cold tolerance, though it can suffer from winter damage in the coldest areas of the northern U.S. and Canada. It can withstand hot temperatures provided it gets adequate water, but extreme heat combined with drought can kill this grass.

Fertilizer

Tall fescue grass will do best if fed yearly at a rate of 2.5 to 3 pounds of nitrogen-based fertilizer per 1,000 square feet of lawn.

Types of Tall Fescue Grass

Many tall fescues were developed for use as pasture fodder for grazing animals. The varieties created for turf lawn use are mostly dwarf varieties of F. arundinacea:

  • 'Black Beauty' is a blend of tall fescues, noted for having good disease resistance.
  • 'Dense Shade Mix' is another blend, noted for good performance in shady locations and for fast growth.

Fescue grass seed is commonly mixed with other cool-season grasses in the North (such as Kentucky bluegrass) to arrive at an ideal blend for lawns. The idea behind such mixes is to draw upon the different strengths of the different kinds of grasses. By doing this, their weaknesses are offset. For example, Kentucky bluegrass holds up well to foot traffic, but the fescue has greater shade tolerance.

Mowing

Cool season grasses such as tall fescue are best kept at 3 to 4 inches in length and should be mowed so that you are removing no more than one-third the total length of the grass blades. Keeping lawn grasses relatively long is the best way to block out weed growth.

How to Grow Tall Fescue From Seed

Tall fescue grows best from seed. Plant when the soil temperature hovers between 50 and 65 degrees Fahrenheit (or about 60 to 75 degrees Fahrenheit for daytime temperatures). Seed it in bare soil, if possible, to a depth of about 1/2 inch. Keep the soil damp while you wait for the seeds to germinate. Wait until blades are 4 inches or more in length before mowing for the first time.

Common Pests and Plant Diseases

Dwarf varieties of fescue commonly used in turfgrass mixes are prone to a fungal disease called brown patch. The symptoms often appear in midsummer, and the only solution is to remove affected patches and reseed.

Common Problems with Tall Fescue Grass

In the right environment, tall fescue can come to dominate other grasses in a mixed-grass lawn. If you need to eliminate tall fescue, there are at least two possible control methods. One is for those who do not mind using chemicals, the other is for those who want to stay organic.

Since tall fescue may already be around in the spring before your Kentucky bluegrass greens up, this is a good time to spray with a glyphosate-based herbicide. Either way, have grass seed ready so that you can reseed and prevent weeds from seizing an opportunity to colonize an empty space in your lawn.

Alternatively, you can practice organic tall fescue control, removing it by digging it out. But be prepared for a workout, because the roots of tall fescue grow thick and deep and do not come out easily. And if you leave little pieces of root behind, the plant can reappear.

FAQ
  • What are alternatives to tall fescue?

    You can opt for ryegrass, Kentucky bluegrass, or even blue fescue for a well-seeded lawn and uniform appearance.

  • How long does tall fescue live?

    Since each blade of grass only lives for 40 days or so, it's important to overseed tall fescue to ensure the best coverage possible.

  • Can tall fescue grow indoors?

    Tall fescue doesn't have a very long lifespan, but during the time it does grow, it can be used as an indoor container plant for visual interest. Make sure it gets ample sunlight.
