Serrated tussock grass (Nassella trichotoma)

Serrated tussock grass

Also known as: Nassella tussock, Yass river tussock

Serrated tussock grass has a long lifespan, lasting over twenty years in the wild. It is commonly found in meadows and pastures, where it has become a pesky weed. Livestock who feed on serrated tussock grass can develop indigestible balls which may lead to death. It is known to be a severe fire hazard, as it burns up to seven times more intensely than native grasses.

Distribution of Serrated tussock grass

Distribution Map

Serrated tussock grass is indigenous to the grasslands of South America. Over time, this plant has transcended its original bounds, finding footing in various other major regions, particularly parts of Europe and the Pacific. Despite its global reach, serrated tussock grass is sometimes thought to be a plant that can gently press upon the natural tapestries of ecosystems where it is not native, especially in certain areas where its presence is prevalent.

Water: Serrated tussock grass thrives in arid South American regions, showcasing exceptional drought tolerance. It develops deep roots to maximize water uptake, requiring weekly watering when cultivated. Preferring well-draining soil, serrated tussock grass endures variable temperatures and benefits from natural rainfall rather than frequent irrigation.

Fertilize: For serrated tussock grass, enrich soil annually with 1-2 inches of mulch or compost, keeping it away from stems. This enhances moisture retention and weed control. Adjust fertilization frequency based on growth stages and seasons, using well-composted organic material to avoid nutrient burn.

Pruning: Serrated tussock grass has long, thin leaves and a dense root system. Prune in early spring to control growth and prevent invasiveness. Cut back old foliage for new growth and maintain shape. Regular pruning minimizes competition and promotes vigor using clean, sharp tools to avoid disease.

Propagation: Serrated tussock grass is an invasive species that spreads primarily through seeds. For successful cultivation, use quality seeds on prepared soil, keeping it moist for germination. Early intervention is key to managing its spread, requiring routine monitoring for new seedlings and implementing control methods as needed.
