Troubleshooting
Jacobinia Carnea problems — and how to fix them
Jacobinia Carnea (Justicia carnea) 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 and bare stems
Without pinching it grows tall and sheds lower leaves, leaving stark stems. Pinch growing tips regularly and cut back hard after flowering to keep it bushy and well-clothed.
Leaf drop from dry air or drought
Low humidity, draughts or a dried-out rootball trigger sudden leaf loss. Keep humidity up, avoid radiators and cold air, and never let the soft stems wilt fully.
Root and stem rot
Soggy, poorly drained compost rots the soft base quickly. Use a free-draining mix, empty saucers after watering and let the surface dry slightly between waterings.
Spider mites
Warm, dry indoor conditions invite spider mites, seen as fine webbing and stippled leaves. Raise humidity, inspect leaf undersides and treat promptly with insecticidal soap.
