Soil Type

Water: Originating from areas with variable moisture, needle grass prefers consistent humidity and has moderate drought tolerance. Watering twice a week meets its hydration needs without over-saturation. As an outdoor plant, needle grass benefits from rain patterns resembling its native climate, aiding in its natural wet-dry cycle.

Fertilize: For needle grass, apply a 2-inch layer of mulch or compost annually to enrich soil. Avoid contact with stems and adjust application with seasonal growth. Water thoroughly after fertilization to ensure nutrient absorption, increasing frequency during warmer months and reducing in cooler ones.

Pruning: Needle grass is a hardy perennial grass with needle-like leaves. Prune in early spring to boost vigor and shape, removing dead stems and thinning clumps for better air circulation. Avoid heavy pruning to prevent stress. Proper care enhances ornamental appeal and growth health.

Propagation: Division is an effective propagation method for needle grass, involving the careful separation of mature clumps into smaller sections with roots and shoots. Use clean, sharp tools to reduce damage, and promptly replant in suitable soil to encourage healthy new growth.
