Crocosmia likes average watering and also thrives well when the soil maintains a moderate level of moisture but not too wet. Water on a regular basis during periods of dry weather particularly when there is active growth of the plants or when the plants are forming buds. The application of a balanced fertilizer at an early spring may contribute to good leaves and a successful flower production. Use of organic compost or slow-release fertilizer is effective to promote the consistent growth through the season and promote the summer blooms.
