Water your crocosmias once weekly during the growing season, so the soil remains evenly moist. Remove spent blooms to encourage new blooms. Cut the stems back to where they meet the leaves. After blooming is over, keep the leaves so that the plant can put its energy back into its bulb for next summer’s blooming.
Hereof, how do you identify Crocosmia?
Crocosmia species are easily recognised when in flower by the distinct shape and colour of their flower heads. All are non-native in the UK.
Similarly, how does crocosmia spread?
Crocosmia corms multiply over the years, forming new corms which grow on top of each other in a ‘conjoined string’. To propagate crocosmia, lift clumps in spring and gently pull the corms apart.
Why did my crocosmia not flower?
There are several reasons why your Crocosmia may not be flowering well. It might be that the plant is congested, and needs to be divided – see above for more information on how to do this. Aim to divide your plant every 3 years to ensure it’s in the best health and maximise flower production.

Crocosmias grow well in most soil types, but do best in soil that retains some moisture in summer. They prefer full sun, but also tolerate dappled or light shade.
Their intense colors contrast well with blue and purple Salvias (Sage), Agapanthus (Lily of the Nile), Geraniums (Cranesbills) or silver foliage plants.
Crocosmia. Cut back flowering stems to near ground level in November, but leave evergreen foliage to provide winter protection – removing it in early March. In cold gardens, lift corms in October.
One of the best-known cultivars, with magnificent scarlet-red flowers borne on long purple-tinted stems. Grows to as tall as 4 feet, making it ideal for the back of the border. The attractive, slightly pleated leaves add textural interest throughout the growing season.
The crocosmia was formerly called tritonia. Insert the shovel as far as possible into the soil around all sides of the hydrated clump to be moved. Lift the entire clump and tear it apart, gently separating all the baby cormels. Each cormel will create a new crocosmia.
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.
Just as spring is the time to plant new corms, it’s also the time to divide and transplant established crocosmia plants. Like other bulb plants, crocosmia needs dividing every two to four years to prevent over crowding. When dividing, it’s important to dig down deep enough to prevent damage to the delicate corms.
