Water: Pacific onion thrives in moist environments, preferring consistent hydration but tolerating brief dry spells. Weekly watering maintains its optimal balance, aligning with natural rainfall. Typically grown outdoors, this robust species benefits from a growing season that prevents overwatering while ensuring adequate moisture.

Fertilize: Fertilize pacific onion bi-annually with balanced fertilizers to enhance growth and flowering. Apply in spring for vigor and before winter for dormancy. Use half the recommended amount, adjusting frequency as pacific onion matures, and ensure even distribution while avoiding the stem to prevent chemical burns. Water consistently post-fertilization.

Pruning: Pacific onion features vibrant blooms and a clumping growth habit. Prune by deadheading and trimming dead foliage in early to late spring to enhance blooming and health. Use clean tools to prevent disease and maintain the plant's natural shape.

Propagation: Pacific onion, native to North American mountain meadows, propagates easily through division. Separate bulbs during dormancy, ensuring root retention for transplanting. Provide fertile, well-draining soil, consistent moisture without waterlogging, and partial to full sunlight for optimal growth and blooming.

Repotting: Pacific onion requires excellent drainage in pots to thrive, ensuring that water does not accumulate and cause root rot.
