Philodendron 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 philodendron, adjust the diagnosis around this plant profile: Philodendrons are forgiving aroids, but yellow leaves often trace back to wet soil, low light, aging vines, or pests tucked into 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 yellowing is limited to old inner leaves or spreading down vines.

Look for sparse growth and long internodes.
