Kikuyu grass

Pennisetum clandestinum

Introduction:

Pennisetum clandestinum, commonly known as kikuyu grass, is a warm-season perennial grass belonging to the Poaceae family. Native to East Africa, it has become widely cultivated and naturalized in various regions around the world. Kikuyu grass is valued for its rapid growth, dense mat-forming habit, and ability to establish quickly in a variety of environments.

Identification:

Appearance: Kikuyu grass is a low-growing, spreading grass with prostrate or ascending stems. The leaves are green, linear, and often have a boat-shaped tip. The plant forms dense, turf-like mats, and during the growing season, it produces characteristic white, star-shaped flowers in clusters.

Distinctive Features:

  1. Growth Habit: Low-growing and spreading, forming dense mats.
  2. Leaves: Linear, green, with a boat-shaped tip.
  3. Flowers: Small, white, star-shaped flowers in clusters.

Habitat and Distribution:

Kikuyu grass thrives in warm, temperate to subtropical climates and is commonly found in lawns, pastures, and disturbed areas. It is well-adapted to a variety of soil types but prefers well-drained soils.

Cultural Uses:

  1. Lawn Grass: Kikuyu grass is popularly used as a lawn grass due to its rapid growth, lush appearance, and ability to form a dense turf.

  2. Pasture: It is utilized as a forage grass for livestock due to its palatability and nutritional value.

Management Strategies:

While Kikuyu grass has desirable characteristics, it can become invasive in certain situations. Here are some management strategies:

  1. Mowing: Regular mowing helps maintain an even and attractive lawn, controls the height of the grass, and reduces the potential for flowering and seed production.

  2. Edging: Creating defined edges around lawns and landscape beds can help contain the spread of kikuyu grass.

  3. Herbicides: Selective herbicides targeting grassy weeds can be used to control kikuyu grass in certain situations. However, care should be taken to avoid damage to desirable vegetation.

  4. Overseeding: Overseeding with other grass species can help diversify the lawn and compete with kikuyu grass.

Caution: While Kikuyu grass is valued for its desirable characteristics, its vigorous growth can lead to invasiveness, especially in areas with favorable climates. It may spread aggressively and outcompete other grass species.
