How to plant crocosmia
Crocosmia is a cormous perennial. Plant crocosmia corms about 8-10cm deep below soil level in early spring. You can leave the corms in the ground to over-winter.
When to prune Crocosmia ( Montbretia ). Cut back the flowered stems after flowering. Leave the foliage intact over the winter. It will provide a bit of winter protection.
Cut the dead foliage to ground level in spring.
Crocosmia will need protection in winter in colder areas. Apply a thick layer of dry winter mulch around the base of the plant to protect from cold.
How do you divide crocosmia. New corms form on the old ones. Dip up the clump and divide in spring. Best to use a strong fork. Replant the biggest corms about 8-10cm deep.
Crocosmia will look good with a range of partners such as Ornamental grasses, Helenium, Rudbeckia, and the Smoke Bush.
