Cactus Transplant Basics: Cactus Mix Soil, Spring Timing, and Pot Size

Soil

Commercial "cactus mix" + 30–50% extra perlite/pumice/coarse sand. Pre-moisten slightly before use.

Timing

Spring (active growth start) or early fall. Avoid winter dormancy and summer heat peaks.

Pot Size

Only 1–2 inches wider than current. Overpotting = wet soil = rot.

Process

1. Dry soil before removing (easier, less root damage).
2. Loosen root ball gently.
3. Place at same depth.
4. Backfill; tap pot to settle.
5. No water 7–10 days.
