Can Crocosmia be pruned or cut way down? When? The tall leaves are looking ungainly.
According to The Plant Care Manual by Stefan Buczacki (Crown, 1993), you should cut back the foliage as it discolors.
According to the Royal Horticultural Society, perennials that produce leaves and flower stems from below the soil level, such as crocosmia and peony, are cut back to soil level.
