Yellowing leaves on a monstera (Monstera deliciosa or Swiss cheese plant) can be caused by overwatering, underwatering, low light or nutrient imbalances.
Don’t let it sit in waterlogged soil or let the soil completely dry out.
Overwatering is the usual culprit – if the soil stays too wet, the roots may suffocate or develop rot, leading to yellow leaves.
If the roots are rotting, you’ll need to repot the plant, trimming away any mushy roots and using fresh, well-draining soil.
If the soil is too dry, thoroughly water your plant, ensuring excess water drains.
