1. Choose the Right Site & Soil
Crocosmia plants relish fertile soil with good drainage. Make sure the location for planting crocosmia bulbs gets full sun for at least 4-5 hours a day. For areas with poor quality soil, I’d recommend adding organic compost or peat moss to enrich the soil.
2. When & How to Plant
Plant in spring after the last frost has passed. If planting dormant corms, set them about three times their depth and 4-8″ (10-20 cm) apart.
3. Spacing, Depth & Grouping
The hole for planting crocosmia bulb should be 4-5 inches deep. Also, allow a separation of 3-4 inches between the plants. This will ensure the plants have ample room for growth. Refill and water generously.
4. Watering & Maintenance
Keep your plants well watered during the early part of the growing plants. Established plants are resistant to drought and should be watered only when the soil appears dry. Mulch the plants after planting. Mulch serves by repelling weeds and retaining moisture in the soil. Remove the mulch in fall and replace it with a thicker layer to help protect the plants from the cold.
5. Supporting, Pruning & Dead-heading
Pruning is an important part of crocosmia care. It helps rejuvenate the plants and allows the opportunity to get rid of the dead and damaged foliage. Make sure to dispose of the discarded foliage at a safe distance.
