Water: Water your crocuses 'Blue Pearl' regularly in spring and fall, ensuring consistent moisture without overwatering to prevent rot. In winter, water if there's no snow, and during summer dormancy, provide minimal water. After planting, water weekly (12 mm) to support corm development, avoiding dry conditions in fall.

Fertilize: Fertilize crocuses 'Blue Pearl' twice during growth: once in fall for root development and again in early spring for leaf growth. Use a slow-release, granular NPK (5:10:5) fertilizer, mixing 1 pound per 45-50 m² of soil, avoiding direct corm contact to prevent rot.

Pruning: Crocuses 'Blue Pearl' are small, vibrant blue flowers that bloom early. Prune in early to late spring after blooms fade, removing spent flowers and damaged foliage to encourage healthy growth. Light pruning maintains vigor and appearance, while heavy pruning can stress the plant.

Propagation: After collecting stigma threads from crocuses 'Blue Pearl', allow the corms to remain in the soil. They can produce offspring corms through vegetative growth. Store harvested corms in a cool, dark, well-ventilated place for up to 4 years, avoiding direct sunlight and high temperatures.
