Repotting Anthuriums: Skip the Stones, Use a Coffee Filter

Repotting an anthurium? Don't add stones to the pot bottom—it actually harms the plant by reducing the "just right" moisture zone.

The Science

Potted soil has three moisture zones: too dry (top), just right (middle), too wet (bottom). Stones shrink the middle zone by raising the saturated layer.

Correct Method

1. Cover drain hole with a pot shard or coffee filter (prevents soil loss).
2. Fill with quality potting mix.
3. Plant at same depth as before.
4. Water thoroughly.

Why This Matters

Anthuriums need consistent moisture—not soggy, not bone dry. Maximizing the optimal moisture zone promotes healthy root growth.
