Common Camas problems — and how to fix them
Common Camas (Camassia quamash) 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.
Basal rot (Fusarium spp.)
Caused by waterlogged soil or overly wet summer dormancy; affected bulbs become soft and discoloured. Lift and discard infected corms, improve drainage, and allow soil to dry between waterings once foliage fades.
Aphids
Can colonise flower stems and foliage in warm spring weather, secreting honeydew and potentially spreading virus. Knock off with a strong water jet or apply insecticidal soap; healthy, well-fed plants are the best defence.
