Repotting a Large, Tipping Cactus: Pot Size and Soil

Browning Base: Often Normal

Woody, brown trunk at soil line is typical aging (corking), not rot – if firm.

Repotting Steps

1. Soil: "Cactus mix" from nursery (Home Depot, etc.) – or DIY: 1:1:1 potting soil, pumice, coarse sand.
2. Pot: Diameter ~2× current pot. Depth similar. Heavy ceramic/terra cotta adds stability.
3. Process: Wrap plant in old carpet/towel. Slide out. Loosen root ball minimally. Center in new pot. Backfill. Top with gravel mulch.
4. Water: Thoroughly once, then only when dry.

Root Bound? Not a Problem

Cacti tolerate tight roots. Larger pot mainly prevents tipping.

Check for Rot

If base is soft/mushy, follow rot rescue protocol (cut, callus, re-root).
