Water: Twincrest onion thrives in rocky slopes and meadows, preferring well-drained soil and moderate drought tolerance. Water weekly to maintain hydration, avoiding over-saturation. Outdoor, twincrest onion benefits from rainfall, but in gardens or containers, proper drainage is essential to prevent root rot during wet seasons.

Fertilize: Fertilize twincrest onion using balanced nutrition fertilizers at the beginning of the growing season. Apply slow-release granules every 6-8 weeks, using one tablespoon per plant, avoiding the stem. Adjust frequency in cooler months and water thoroughly post-application. Wear gloves for safe handling.

Pruning: Twincrest onion is a perennial with distinctive bulbs and attractive flowers. For best results, prune in early to late spring, removing dead leaves and spent stalks. Cutting back foliage post-flowering promotes energy to bulbs, enhancing vigor and aesthetic appeal in the garden.

Propagation: Twincrest onion thrives through bulb division. After foliage wilts, gently separate the clusters, ensuring root portions remain intact. Replant immediately at the same soil depth to promote robust growth and an abundant crop.

Repotting: Twincrest onion requires excellent drainage in pots to thrive. Ensuring proper drainage helps prevent overwatering and root rot, critical for maintaining healthy growth.
