Grafted Cactus Basal Rot: Top Scion Likely Lost Too

Grafted Plant Reality

8-inch grafted cactus with basal rot = rootstock dead. Scion (top) rarely survives on own roots (no chlorophyll).

Last-Ditch Attempt

1. Cut scion off cleanly below graft union.
2. Callus 2 weeks.
3. Attempt root in moist peat-perlite under humidity dome.
4. Success rate <10%.

Better Plan

Buy new grafted plant. They're inexpensive and widely available. Learn watering restraint: monthly max indoors, dry soil mandatory.
