Monstera Subpinnata problems — and how to fix them
Monstera Subpinnata (Monstera subpinnata) 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.
Leaves staying solid (no splits)
Usually too little light or no support to climb. Move to brighter indirect light and add a moss pole to encourage mature, divided foliage.
Crispy lobe edges
A sign of low humidity or underwatering. Raise ambient humidity above 60% and keep the mix evenly moist during active growth.
Yellowing lower leaves
Typically overwatering or poor drainage. Let the top few centimetres dry between waterings and ensure the chunky mix never stays sodden.
Spider mites
Dry indoor air invites mites on the fine foliage. Inspect leaf undersides, rinse the plant and treat with insecticidal soap if fine webbing appears.
