Can I revive my crocosmia? Anne Swithinbank explains how
Check old, untended clumps of crocosmia that push themselves above soil level and become vulnerable to extremes of cold and dryness. 2
Exposed to any long hot, dry periods, crocosmias in sheltered positions often succumb to red spider mite. Look for pale, almost scorched-looking foliage, and check with a hand lens. 3
Lift a portion of a crocosmia clump, and you can see successive layers of corms one on top of the other. Technically, these could all make new plants. 4
Lift and divide after flowering or water well if dry. Draw soil up the sides to insulate the clump. Dispose of leaves after they’ve turned brown, and divide in spring.
