Troubleshooting
Crossandra (firecracker flower) problems — and how to fix them
Crossandra (firecracker flower) (Crossandra infundibuliformis) 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.
Sudden leaf or flower drop
Usually from letting the soil dry out completely, cold draughts, or temperatures dipping below about 13-15°C.
Yellowing lower leaves
Typically overwatering or soggy soil, which suffocates roots and can lead to root rot.
Few or no flowers
Most often caused by too little light, though missing a slightly cooler, drier winter rest can also reduce spring blooming.
Spider mites
Dry indoor air invites these sap-suckers, seen as fine webbing and pinpoint yellow speckling under leaves.
Mealybugs, aphids and whitefly
Sap-feeding insects that cluster on new growth and leaf undersides, leaving sticky honeydew and sometimes sooty mould.
Crispy brown leaf edges
A sign of low humidity or under-watering in warm, dry rooms.
