Grafted Cactus Overwatered: Scion Regraft Attempt, Rootstock Lost

Graft Anatomy Limits Options

Rootstock (base) rotted. Scion (top) lacks chlorophyll — cannot root alone.

Only Attempt: Regraft

1. Cut scion below graft union.
2. Callus 1–2 weeks.
3. Graft onto new rootstock (Myrtillocactus).
4. Humidity dome 2 weeks.

Realistic: Replace

Regrafting is advanced. New grafted plant = $10–20. Lesson: water by soil dryness, not schedule.
