Water thoroughly after planting corms in autumn and keep the soil consistently moist during the growing season (winter and early spring). Reduce watering significantly once the foliage begins to yellow and die back in late spring, allowing the corms to go dormant.

No pruning is required for Crocus angustifolius. After flowering, allow the foliage to die back naturally to replenish the corm's energy reserves for the following season.

Remove dead or withered leaves only once they have completely yellowed and dried.

Crocus angustifolius naturalizes readily from its corms. To propagate, carefully divide the corm clumps in late summer when they are dormant.

Replant the divisions immediately at the appropriate depth, ensuring good drainage and sun exposure.

Repotting is generally not necessary for established plantings as they naturalize well. If growing in containers, repot every 2-3 years in late summer to refresh the soil and divide overcrowded corms.

Use a well-draining potting mix.
