Water: Spiked oatgrass thrives with consistent hydration, requiring weekly watering to maintain health. Adapted to cyclical moisture, it balances water needs without drought tolerance. This species is resilient against temperature fluctuations, making it suitable for outdoor cultivation during unpredictable rainy seasons.

Fertilize: For optimal growth, spiked oatgrass benefits from annual mulch or compost application in early spring. Apply a 2-inch layer around the base, avoiding the crown. Moderate fertilization during active growth is essential, while monitoring spiked oatgrass's response and adjusting for lower nutrient needs in dormant seasons.

Pruning: Spiked oatgrass is a tufted perennial grass valued for its decorative seed heads. Prune in early spring to remove dead foliage, encouraging new growth and preventing disease. Regular trimming enhances its appearance, promoting vigorous regrowth while avoiding heavy pruning during active growth to reduce stress.

Propagation: Spiked oatgrass thrives as a hardy perennial when propagated by seed in well-draining soil. Lightly covering seeds and maintaining consistent moisture encourages germination. Careful transplanting of seedlings fosters robust root development, mirroring the plant's natural regeneration process.
