Repotting Anthuriums: When and How to Transplant

When to Repot

Repot immediately if severely rootbound (roots circling surface, growing through drainage holes, wilting after watering, water runs straight through, cracked pot). If just crowded, wait until new growth emerges in spring.

How to Repot

1. Choose a pot 1–2 inches larger in diameter.
2. Cover drainage hole with mesh, paper towel, or coffee filter.
3. Water plant well a few hours before repotting.
4. Use a light, loose mix (pH ~6.5): e.g., 2 parts orchid mix, 1 part peat, 1 part perlite; or equal parts peat, pine bark, perlite.
5. Add enough new soil so rootball sits ~1 inch below rim.
6. Gently remove plant; tease compacted roots.
7. Place in new pot; fill around rootball; firm lightly.
8. Water lightly to settle; add more soil if needed. Keep rootball at same level—planting crown too deep causes rot.
9. Place in shade for a couple days; slight wilting is normal.
10. Withhold fertilizer for 2 months.
