Soil Type

Water: Toothache grass thrives in tropical habitats with high humidity and regular moisture. It prefers consistent hydration, requiring weekly watering to promote lush growth. Well-suited for moist environments, toothache grass has a root system that efficiently absorbs water, enhancing its resilience during rainy seasons.

Fertilize: To thrive, toothache grass needs careful fertilization, ideally with organic mulch or compost for slow-release nutrients. Apply a 2-inch layer quarterly, avoiding the base to prevent rot, and adjust for seasons. Always water toothache grass post-fertilization to enhance nutrient absorption for healthier growth.

Pruning: Prune toothache grass in early spring by removing dead or damaged stems to encourage healthy growth. Regular trimming maintains size and enhances airflow. Focus on older parts for new shoots, and prune after the last frost to reduce stress and disease risk, promoting vigorous, year-round health.

Propagation: Toothache grass is a perennial grass with medicinal properties, propagated by division. Split dense root clumps during active growth, ensuring each section has sufficient roots and shoots. Careful handling minimizes stress, promoting faster recovery and robust growth in new environments.
