Water: Orangegrass prefers consistent hydration without over-saturation, thriving in balanced moisture regimes. With moderate drought tolerance, it adapts well to ambient humidity. Weekly watering maintains optimal hydration, particularly when grown outdoors, aligning with seasonal rainfall to ensure adequate moisture during growth cycles.

Fertilize: For optimal growth, orangegrass requires balanced fertilizers and high-nitrogen formulas during growth phases, applied every 4-6 weeks. Use quarter-strength solutions to prevent root damage and reduce application in winter. Dilute concentrates and water soil prior to fertilization, following product guidelines for best results.

Pruning: Orangegrass features slender stems and small yellow flowers, thriving with minimal pruning. Trim in early to late spring to promote growth, remove dead stems, and improve airflow. Regular pruning enhances health and flowering; ensure to use sterilized tools to avoid disease.

Propagation: This perennial herb, orangegrass, thrives in diverse habitats. For best propagation, sow in light, well-draining soil and maintain moisture without overwatering. Lightly cover seeds with sand or gravel to enhance germination. Once seedlings grow, provide ample space for root development to promote healthy growth.
