Montbretia 'Lucifer' problems — and how to fix them
Montbretia 'Lucifer' (Crocosmia x crocosmiiflora) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Corm rot
Caused by waterlogged soil; improve drainage and avoid overwatering, especially in autumn and winter.
Spider mites
In hot, dry weather fine webbing may appear on foliage; increase air circulation and mist foliage, or use an insecticidal soap spray.
Invasive spread
Corms multiply rapidly and can become invasive; divide clumps every 3-4 years in spring to keep plants vigorous and controlled.
Frost damage to corms
In colder climates (USDA zone 5 and below), lift corms in autumn and store frost-free over winter.
Poor flowering
Usually caused by overcrowding or too much shade; divide clumps and move to a sunnier position.
