Water:
American needle-grass thrives in arid regions with exceptional drought tolerance. It requires weekly watering to stay healthy, even as an evergreen that retains foliage year-round, necessitating consistent hydration through colder months.
Fertilize:
American needle-grass thrives with annual mulch or compost application in early spring, about 5-7.5 cm (2-3 inches) around its base, avoiding stem contact. This promotes healthy growth, soil structure, and nutrient absorption. Additional feeding may be needed during active growth; avoid over-fertilization. Wear gloves to prevent skin irritation.
Pruning:
American needle-grass has slender, needle-like foliage and benefits from early spring pruning. Trim old or damaged stems to foster new growth, improve air circulation, and prevent fungal issues. Regular pruning maintains tidiness and enhances the plant's overall health and resilience.
Propagation:
American needle-grass can be propagated through division by separating a dense clump into smaller sections. Carefully dig up the root mass, divide it with a sharp tool, and ensure each part has roots and shoots. Plant in well-draining soil and water consistently for establishment.
