Fast-Rotting Variegated Euphorbia: 5-Inch Clear-Cut Rule and Alcohol Sterilization

Aggressive Cutting Protocol

1. Cut 5–6 inches above ANY discoloration/softness.
2. Inspect cut face: black spots? Recut 5–6 inches higher.
3. Alcohol-sterilize blade BETWEEN EVERY CUT.
4. Callus 2+ weeks.
5. Root in NEW soil, dry regime.

Why 5 Inches?

Euphorbia latex transports rot internally faster than cacti. Wider margin essential.

Causes

Overwatering or cold. Variegated forms more sensitive.
