Tall Fescue Grass In The Lawn: How to Grow and Maintain It
If you are looking for a lawn grass that can thrive in the cool season, tall fescue grass can be an excellent choice. With its deep roots and durable nature, it can withstand drought, heavy traffic, and pests. However, growing and maintaining tall fescue grass requires some knowledge and effort. In this article, we will guide you through the process of planting, caring, and troubleshooting your tall fescue lawn.
Choosing the Right Variety of Tall Fescue Grass
Before starting to plant tall fescue grass, you need to select the right variety that matches your climate, soil, and usage. There are two main categories of tall fescue grass: turf-type and tall-type. Turf-type tall fescue is finer and denser in texture, making it suitable for ornamental lawns. Tall-type tall fescue has broader blades and taller growth habit, making it ideal for sports fields and pastures. Both types have their advantages and disadvantages, so you should consult with a local nursery or extension office to determine which one suits your needs best.
Another factor to consider when choosing tall fescue grass is its seed blend. Some blends contain only tall fescue grass, while others may include other cool-season grasses such as Kentucky bluegrass, perennial ryegrass, or fine fescue. A mixed seed blend can provide more diversity in color, texture, and disease resistance, but it may also require more maintenance and watering.
Preparing the Soil and Planting Tall Fescue Grass Seeds
Once you have decided on the variety and seed blend of tall fescue grass, you need to prepare the soil for planting. Tall fescue grass prefers well-drained, slightly acidic soil with a pH range of 6.0 to 7.5. You can test your soil pH and fertility levels with a soil test kit or send a sample to a soil testing lab for analysis.
Next, you need to remove any existing vegetation, debris, or rocks from the planting area. You can use a sod cutter, tiller, rake, or hoe to loosen the topsoil and create a smooth surface. If you have poor soil quality, you may need to amend it with organic matter such as compost, peat moss, or aged manure. Spread a layer of 1-2 inches of organic matter over the soil and mix it thoroughly with a shovel or fork.
After preparing the soil, you can start sowing the tall fescue grass seeds. The best time to do this is in the late summer or early fall, when the soil temperature is around 60-75°F and the rainfall is abundant. You can either broadcast the seeds by hand or use a seed spreader to ensure even distribution. The recommended seeding rate for tall fescue grass is 6-8 pounds per 1000 square feet for pure stands and 4-6 pounds per 1000 square feet for mixed stands. After spreading the seeds, lightly rake them into the soil to ensure good seed-to-soil contact.
Caring for Tall Fescue Grass
After sowing the tall fescue grass seeds, you need to take care of them properly to ensure successful germination and establishment. Here are some tips for caring for your tall fescue lawn:
Watering
Water your newly planted tall fescue grass seeds frequently and deeply to keep the soil moist. You may need to water twice a day for the first two weeks or until the seeds have germinated and the shoots have reached 2-3 inches in height. After that, you can reduce the frequency but increase the duration of watering sessions. Aim to provide 1-1.5 inches of water per week, either from rainfall or irrigation. Avoid overwatering or watering at night, as this can lead to fungal diseases and shallow root growth.
Fertilizing
Fertilize your tall fescue grass regularly with a balanced fertilizer that contains nitrogen, phosphorus, and potassium in a ratio of 3:1:2 or 4:1:2. Apply the fertilizer according to the label instructions, usually every 6-8 weeks during the growing season. Avoid applying too much fertilizer, as this can burn the grass and pollute the environment. You can also use organic fertilizers such as compost tea, fish emulsion, or bone meal, which release nutrients slowly and improve soil health.
Mowing
Mow your tall fescue grass when it reaches a height of 3-4 inches and remove no more than one-third of the blade length. Use a sharp mower blade and set the cutting height at 2-3 inches for turf-type tall fescue and 3-4 inches for tall-type tall fescue. Mow regularly, at least once a week during the growing season, and vary the direction and pattern of mowing to avoid creating ruts or compacted soil. Leave the clippings on the lawn, as they can decompose and recycle nutrients back into the soil.
Aerating
Aerate your tall fescue lawn once a year to alleviate soil compaction and improve air and water circulation. You can use a manual or motorized aerator that punches holes or plugs into the soil. Aerating is especially important if you have heavy clay soil, high foot traffic, or thatch buildup. Aerate in the fall or spring when the grass is actively growing and the soil is moist but not saturated.
Weeding and Pest Control
Weed your tall fescue lawn regularly to prevent the invasion of broadleaf weeds such as dandelions, clover, or chickweed. You can use herbicides that are labeled for tall fescue grass and follow the instructions carefully. Alternatively, you can pull weeds by hand or use natural weed control methods such as mulching, overseeding, or using vinegar or boiling water. For pest control, monitor your lawn for signs of insect infestations or diseases such as brown patch, dollar spot, or rust. Consult with a professional landscaper or extension agent for proper identification and treatment options.
Troubleshooting Common Problems with Tall Fescue Grass
Even with proper care, your tall fescue lawn may encounter some common problems that affect its appearance and health. Here are some tips for troubleshooting these problems:
Bare Spots or Thin Areas
If your tall fescue lawn has bare spots or thin areas, you can reseed them by loosening the topsoil with a rake or aerator and filling them with fresh seed. Water and fertilize the newly seeded areas regularly and avoid walking or mowing over them until the grass is established.
Diseases
If your tall fescue grass is infected with diseases such as brown patch or rust, you can treat them with fungicides that are specific to the disease and safe for grass and humans. Follow the application instructions and wear protective gear when handling chemicals. You can also prevent diseases by improving the soil drainage, reducing the watering frequency, and promoting air circulation and sunlight exposure.
Insects
If your tall fescue grass is attacked by insects such as grubs or chinch bugs, you can use insecticides that are labeled for tall fescue grass and apply them according to the label instructions. You can also use natural insect control methods such as nematodes, milky spore, or beneficial insects such as ladybugs or lacewings. Prevent insect infestations by keeping your lawn healthy, avoiding overfertilization, and reducing the thatch buildup.
Tall fescue grass can be a great addition to your lawn if you know how to grow and maintain it properly. By selecting the right variety, preparing the soil, planting the seeds, and taking care of your tall fescue lawn, you can enjoy a lush, green, and durable carpet of grass all year round. Remember to water, fertilize, mow, aerate, weed, and monitor your lawn regularly, and troubleshoot any problems promptly. With patience, persistence, and passion, you can create a beautiful and healthy tall fescue lawn that enhances your property value and your outdoor enjoyment.
