Rooting Cactus Cuttings: Callusing and Planting

For any cactus cutting:

1. Let cut ends callus (dry, turn brown) for ~1 week in air and light.
2. Plant in dry cactus mix; water lightly after a few days.
3. Allow soil to dry completely between waterings.

Both ends of a segment can root. The greener end may root faster, but either works. Cacti root quickly in warm, bright conditions.
