Sunburn on monstera deliciosa — Fix & Prevention

What's Happening

Monstera deliciosa is a slow-acclimating evergreen. Its ability to move carbon from leaves is limited by loading vein density. Moving a plant from low light to high light too quickly causes a bottleneck where the leaf cannot export energy fast enough, leading to non-photochemical quenching (NPQ) failure and solar radiation damage (sunburn).

How to Fix It

1
Gradually increase light exposure over 10-14 days.
2
If sunburn occurs (bleached or brown crisp patches), move to a slightly shadier spot and do not remove the leaf unless it is >50% damaged, as it still supports the plant.
3
Ensure adequate hydration during acclimation to support transpiration.

How to Prevent It

Monitor the geniculum: if the leaf folds back against the petiole, the light is too intense. Use sheer curtains to diffuse direct noon sun.
