Why Houseplant Leaves Turn Yellow After Watering

Three Common Causes

1. Standing water in saucer: Roots suffocate, can't deliver CO₂ to leaves → yellowing.
2. Extreme dry-down before watering: Delayed stress response.
3. Insufficient light: Plant can't support foliage.

Diagnose Your Routine

• Empty saucers 1 hr after watering.
• Water when top 1–2" dry (not bone dry).
• Ensure bright, indirect light for most tropicals.

Identify your plants (email photos if unsure) for specific advice.
