Euphorbia Cutting Failure: Mandatory 3-Week Callus, Rot Inspection, and Latex Management

Critical Errors in Original Attempt

• 1-day callus (need 3–4 weeks).
• No cut-face inspection for rot.
• Watering too soon.

Correct Protocol

1. Cut into green, non-woody stem.
2. Inspect cut: any brown/black? Recut 1+ inch higher until clean.
3. Sterilize blade between cuts.
4. Callus 3–4 weeks horizontal in shade.
5. Cut end must be HARD and dry.
6. Plant 1+ inch deep in dry gritty mix.
7. Water once; then only when bone-dry.

Latex = Rot Vector

Euphorbia latex spreads rot internally. Extended callus lets latex seal off. Small cuttings = higher risk.
