Water: French oat-grass prefers consistent moisture, thriving with regular hydration cycles and moderate drought tolerance. Water weekly to emulate natural conditions. Predominantly outdoor, it benefits from rainwater during its active growth, enhancing resilience and root system strength.

Pruning: French oat-grass features slender, fragile stems and requires annual pruning in early to late spring for optimal vigor. Remove dead or damaged stems and overgrowth to promote healthy growth. Pruning enhances appearance, improves air circulation, and reduces disease risk. Use clean, sharp tools for cutting.

Propagation: French oat-grass is a perennial grass propagable by sowing healthy seeds. Use a well-draining soil medium and keep it consistently moist until germination. Thinning seedlings promotes healthy growth and allows for strong root development.
