Troubleshooting
Plectranthus Oertendahlii problems — and how to fix them
Plectranthus Oertendahlii (Plectranthus oertendahlii) 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.
Legginess
Stems can stretch and go bare-centred, especially in low light. Pinch the growing tips regularly and give bright, indirect light to keep the plant dense and well-clothed with leaves.
Stem and root rot
Overwatering or heavy, soggy compost rots the soft stems and roots. Let the surface dry between waterings, use a free-draining mix and never leave the pot standing in water.
Faded leaf colour
In too little light the silvery veins and purple undersides become muted. Move to a brighter, filtered position to restore the strong leaf markings.
Mealybugs
Cottony mealybugs can hide in leaf axils and along stems. Inspect regularly and dab pests with a cotton bud dipped in dilute alcohol, or treat with insecticidal soap.
