When should crocosmia be divided?
Crocosmia corms multiply readily, so clumps will become congested and flower less vigorously over time. The best time to divide and replant congested clumps is in spring.
How do you divide and replant crocosmia?
Crocosmia and Dierama
- Divide Crocosmia and Dierama in spring.
- To remove the corms without damage, dig down 30cm (1ft) to avoid and gently lift.
- The roots of both perennials form ‘chains’ of corms, which can be replanted intact or individually separated.
- Discard wizened or diseased corms and trim old leaves.
When can you separate crocosmia bulbs?
Propagate by division in spring just before growth starts. Crocosmia should only be divided every 3-4 years (in late summer or early fall), to restore vigor and increase flower production.
Does crocosmia transplant well?
Crocosmia can be divided and replanted in spring before it enters the active growth period. To do so, dig into the ground around the plant to a depth of 30cm. Carefully detach and remove some of the plant’s corms, or in the case of the Lucifer cultivar, the underground stems and roots.
What do you do with crocosmia in the winter?
Crocosmia hardiness varies according to species, but here in Sussex I leave all of mine in the ground in winter, giving them a good, deep mulch before the autumn frosts. In frost pockets, lift the corms in autumn and store them over winter in a frost-free place to plant again in mid-spring.
Can crocosmia be split?
You can split these corms apart in spring or late autumn before new growth appears every two to three years. Splitting, or dividing, the corms provides you with new plants and prevents the bed from becoming crowded.
Do you cut back crocosmia in the fall?
Crocosmia. Cut back flowering stems to near ground level in November, but leave evergreen foliage to provide winter protection – removing it in early March.
