In full sunlight, this plant grows better and produces high-quality forage.

Temperature Requirements

The ideal temperature for Festuca rubra L. var. arenaria growth ranges between 10°C to 25°C. The plant requires cool temperatures for optimal growth, making it suitable for cool-season pastures. It can tolerate and grow in colder temperatures and survive up to -20°C temperatures. However, high temperatures can cause stress, leading to reduced growth rates.

Soil Requirements

Festuca rubra L. var. arenaria grows well in sandy and well-drained soils with a pH ranging from 5.5 to 7.5. It thrives in soil with high organic matter content. The soil should be fertile and have good moisture-holding capacity. Poorly drained soils should be avoided since they can lead to root rot. This plant can also tolerate slightly acidic soils, but extreme acidity can reduce its growth rate.

Cultivation Methods

Festuca rubra L. var. arenaria (Osbeck) Fries, commonly known as red fescue or creeping red fescue, is native to Asia and Europe. This plant is relatively easy to cultivate and its growth and development can be supported by a well-prepared and well-drained soil. The ideal soil for red fescue should be slightly acidic, with a pH range of 5.0 to 6.0.

The plant is tolerant of moderate to heavy shade and can be planted in areas where it is difficult to grow other types of grass. The plant spreads through rhizomes, and it can be propagated by seed or division. When propagated by seed, it is recommended to sow the seeds in spring or early fall when the soil temperature is between 60°F and 75°F.

Watering Needs

Red fescue has low to moderate water requirements and can tolerate drought conditions to a certain extent. The amount of watering required by this plant is dependent on the climate and soil moisture conditions. As a general rule, the plant should be watered when the soil surface starts to dry up, but the soil should not be kept soggy. It is recommended to apply water deeply and less frequently rather than shallow and frequently.

Fertilization

Red fescue has moderate fertility requirements. The plant can be fertilized with a balanced fertilizer, such as a 10-10-10, or a high-nitrogen fertilizer, such as a 20-10-10, depending on soil fertility and growth requirements. It is recommended to fertilize the plant in spring using a slow-release fertilizer to promote uniform growth and development.

Pruning

Red fescue is a low-growing, clump-forming perennial grass that requires minimal pruning. However, as with any grass, the plant benefits from an occasional mowing to promote dense growth and to remove dead or yellowing foliage. It is recommended to mow the plant to a height of 2 to 3 inches during the growing season, but the mowing frequency should be reduced during the summer months to prevent excessive sun damage.
