Quick answer: Anthurium leaves often yellow after repotting because roots were disturbed and the new mix is staying too wet. Check root firmness, pot size, airflow, and whether the oldest leaves are the only ones fading.
Normal vs concerning yellowing
- One old lower leaf: usually normal
- Multiple leaves at once: check roots
- Yellow plus soft petiole: urgent
- Yellow plus crisp edge: humidity or watering swing
What to check first
- Is the pot too large?
- Is the mix chunky enough?
- Did roots break during repot?
- Is the crown sitting too deep?
- Is the plant in lower light now?
How to stabilize it
- Keep light bright but indirect
- Water only when the mix begins to dry
- Increase airflow
- Avoid fertilizer for 2-3 weeks
- Do not repot again unless roots smell sour
Sarah's grower note
- Anthuriums like airy roots more than constant moisture.
- Repotting should reset the root zone, not bury it.
Next steps
- Change one variable at a time.
- Take a photo before and after each care adjustment.
- Use the Wild At Home care guides when you need a second check.

FAQ
Should I cut yellow Anthurium leaves?
Remove fully yellow leaves, but wait on partly green leaves if the plant is still using them.
Can overwatering cause yellow leaves after repotting?
Yes. A fresh mix that stays wet can reduce oxygen and stress roots.
How long does repot shock last?
Mild shock may last one to three weeks if roots are healthy.
