Description
Nassella Trichotoma, also known as Serrated Tussock, is an invasive grass native to South America. It has become a significant problem in Australia, New Zealand, and the United States due to its ability to outcompete and displace native plants. The grass has serrated leaves that are green or bluish-green and can grow up to 1 meter in height. Nassella Trichotoma can also produce dense seed heads, which can spread quickly and easily.

Appearance
Nassella Trichotoma has long, serrated leaves that are green or bluish-green in color. The leaves grow in a clump and can reach up to 1 meter in height. The grass can also produce dense seed heads that are up to 30 cm long and have a distinctive purple color. The seed heads can spread quickly and easily, making the grass difficult to control. Nassella Trichotoma is often mistaken for other grasses, so it is essential to identify it correctly.

Nassella Trichotoma is an invasive grass and should not be planted intentionally. If you have this grass on your property, it is essential to control its spread. Here are some tips for managing Nassella Trichotoma:
- Water: Nassella Trichotoma is drought-tolerant and can survive in dry conditions.
- Fertilization: Do not fertilize the grass, as this can encourage its growth.
- Soil: The grass can grow in a variety of soils, but it prefers well-drained soils.
- Sunlight: Nassella Trichotoma can grow in full sun or partial shade.
- Hardiness Zones: The grass can tolerate a variety of hardiness zones, but it prefers warmer climates.
Common Pests & Diseases
Nassella Trichotoma is relatively pest and disease-free, but it can be susceptible to fungal infections in humid conditions. The grass is more likely to suffer from mechanical damage due to mowing or grazing.
Habitat
Nassella Trichotoma is native to South America but has become invasive in several countries worldwide. The grass can grow in a variety of habitats, including grasslands, open forests, and disturbed areas. It prefers dry conditions and can tolerate a range of soil types.
Question and Answer
Q: Is Nassella Trichotoma poisonous?
A: No, Nassella Trichotoma is not poisonous, but it can displace native plants and reduce biodiversity.
Q: How can I control Nassella Trichotoma?
A: The best way to control Nassella Trichotoma is to prevent its spread. This can be done by removing the grass manually or using herbicides. It is important to remove the grass before it produces seed heads.
Q: Can Nassella Trichotoma be used for grazing?
A: Nassella Trichotoma is not recommended for grazing, as it can reduce the productivity of pastures and displace native plants.
Q: Is Nassella Trichotoma a fire hazard?
A: Yes, Nassella Trichotoma can be a fire hazard, as it can produce dense fuel loads that can ignite easily.
