Cynodon Aethiopicus Clayton & Harlan

Overview

Cynodon aethiopicus Clayton & Harlan, also known as African bermudagrass, is a perennial grass species that is highly valued for its ability to thrive and provide ground cover in harsh environments. It is a member of the Poaceae family and is native to Africa, specifically the tropical and subtropical regions.

Common Names

African bermudagrass is known by several common names including African couch, Ethiopian goosegrass, and Sudan grass.

Appearance

The African bermudagrass is a robust and tough grass with a creeping habit that can grow up to 2 feet tall. It has a dark green color and has shiny and smooth leaves that are about 3mm wide and 20-40mm long. It can root and spread through stolons.

Uses

Cynodon aethiopicus Clayton & Harlan has several uses, including erosion control, ground cover, and forage. It is commonly used for stabilizing slopes and preventing soil erosion due to its extensive rooting system. This plant is also used as a ground cover in areas where other plants struggle to grow. In some African countries, this grass is used as forage for cattle due to its high protein content and palatability. It can also be utilized for hay production.

Light Requirements

Cynodon aethiopicus requires full sunlight exposure to grow effectively. It cannot thrive in shaded areas and would require at least 6 hours of intense sunlight daily. The plant requires adequate light for photosynthesis, which is an essential process for its survival.

Temperature Requirements

The plant is extremely heat-tolerant and can grow in regions with high temperature and low humidity. It can tolerate temperatures as high as 40°C without any adverse effects on plant growth. However, the plant is not cold-tolerant and would not survive in regions with frost or a temperature range below 15°C.

Soil Requirements

Cynodon aethiopicus requires well-draining soil with a pH range of 5.5–7.5. The plant can grow in a variety of soil types, including sandy, loamy, and clayey soils. It can also tolerate saline soil conditions, making it highly adaptable to different soil varieties. However, the soil must be fertile and rich in organic matter for the plant to grow optimally.

Cultivation Methods

The Cynodon aethiopicus Clayton & Harlan, commonly known as Sweet Smelling Couchgrass, is a low-maintenance ornamental grass that's comparatively easy to cultivate. It is an ideal choice for both novice and seasoned gardeners. For optimal growth, plant this grass in full sun and keep the ground relatively dry and well-draining. Planting this grass in the spring will provide you with the best results.

Watering Needs

Cynodon aethiopicus prefers dry soil conditions and does not require excessive watering. However, while newly planted, the plant requires consistent moisture to establish itself. Making sure that the soil is damp to the touch is a good barometer for the plant's water requirements.

Fertilization

Couchgrasses will thrive in nutrient-poor soils, but giving a well-balanced fertilizer is beneficial. Apply a slow-release fertilizer, such as a 10-10-10 blend, in the early spring before the growing season begins. If the plant begins displaying stunted growth and yellowing leaves, add more fertilizer.

Pruning

Cynodon aethiopicus grasses do not require frequent pruning, but sporadic removal of wilting growth is beneficial to maintain its form and structure. Pruning should typically be done in the early spring or late winter before the growing season begins. Use pruning shears to clip any dead, diseased, or crossed-over stems.

Propagation of Cynodon aethiopicus Clayton & Harlan

Cynodon aethiopicus Clayton & Harlan, commonly known as African Bermuda grass, is a warm-season perennial grass native to Africa. With its exceptional tolerance to drought and intense heat, this grass can thrive in harsh environments, making it a go-to choice for lawns, pastures, and erosion control.

Propagation Methods

There are three primary methods of propagating Cynodon aethiopicus:

1. Vegetative propagation: This is the easiest and the most common method of propagating Cynodon aethiopicus. The plant spreads through stolons, which are stems that grow horizontally above the ground before rooting to produce new plants. The stolons can be cut into pieces and replanted to establish new grass.
2. Seed propagation: Cynodon aethiopicus produces seeds, but they are not usually used for propagation, as the grass is not true-to-type, meaning that the new plants may not have the same desirable traits as the parent plant.
3. Sod propagation: This method involves cutting and replanting entire sections of turf, which is useful in establishing a lawn or for areas where vegetative propagation may not be practical.

Regardless of the method used, propagation should be done during the warm season when the grass is actively growing.

Disease Management

Like all plants, Cynodon aethiopicus may be subject to various diseases. The most common diseases of this plant include leaf spot, rust, and Pythium root rot.

Leaf spot is when circular spots appear on the leaves and turn yellow then brown over time. Copper-based fungicides can be used to manage this disease.

Rust appears as yellow spots on the leaves and may also affect the stems. Fungicides containing chlorothalonil are effective in controlling rust.

Pythium root rot causes wilting and yellowing of the leaves and can ultimately kill the plant. This disease is caused by a fungus-like organism in the soil and is managed by improving drainage and using fungicides containing metalaxyl.

Pest Management

Cynodon aethiopicus may also be subject to pest attacks. Common pests of this plant include mole crickets and armyworms.

Mole crickets are insects that burrow into the soil and feed on the roots and stems of plants, causing significant damage. This pest can be managed using insecticides containing chlorpyrifos.

Armyworms are caterpillars that feed on the leaves of plants, causing significant damage if left unchecked. Insecticides containing bifenthrin are effective in controlling armyworms.

Regular monitoring of the plant is essential for early detection of diseases and pests. It is essential to read and follow the label instructions when using any chemical control measure to avoid damage to the plant and the environment.
