Diagnosing Yellow Leaves on Houseplants: The Three Main Causes

Yellow Leaves = Light, Water, or Water

Universal causes of yellowing:

1. Not enough light – plant can’t photosynthesize.
2. Too much water – roots rot, nutrients can’t move.
3. Too little water – plant cannibalizes older leaves.

To Diagnose, Provide:

• Plant names.
• Pot sizes.
• Distance/direction from window.
• Watering frequency/amount.

With details, a specific fix is possible.
