Harlequin Flower problems — and how to fix them
Harlequin Flower (Sparaxis tricolor) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Corm rot
The leading cause of failure; caused by moisture during summer dormancy. Always dry corms completely before storing or in a pot, and ensure the container has drainage holes with no saucer left filled with water.
Aphids
Young flower stems and buds are attractive to aphids in spring; check weekly and treat with an insecticidal soap spray or introduce biological controls such as Aphidius wasps under glass.
