Plant + symptom guide

Monstera yellow leaves

Yellow leaves are a pattern, not a diagnosis. On this plant, read them against soil moisture, light level, leaf age, drainage, and recent care changes.

For monstera, adjust the diagnosis around this plant profile: Monsteras usually need bright indirect light, an airy mix, and careful watering. Yellow leaves often come from wet soil, low light, dense mix, or pests on new growth.

How to confirm it

Check whether yellowing starts on old lower leaves or appears across new growth too.

Feel the soil below the surface before watering again.

Look for a recent move, seasonal light drop, or a pot that stays wet.

Check whether the mix is chunky or compacted around the roots.

Inspect unfurling leaves and undersides for thrips or mites.
