Troubleshooting
African Crossandra problems — and how to fix them
African Crossandra (Crossandra nilotica) 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.
Failure to bloom
Almost always caused by insufficient light. Move the plant to a brighter spot with some direct morning sun. Low temperatures below 18°C also suppress flowering.
Root rot
Overwatering or poorly draining soil leads to yellowing lower leaves and mushy stems. Always ensure the pot has drainage holes and allow the soil surface to dry slightly between waterings.
Spider mites in dry air
Fine webbing on leaf undersides indicates spider mites, especially when indoor air is dry. Increase humidity, wipe leaves with a damp cloth, and treat with insecticidal soap if the infestation is established.
