Trimming a Tall, Thin Cactus: Etiolation Correction and Cutting Propagation

Diagnosis: Etiolation from Low Light

Thin, bending stem = stretching for light. Trimming fixes the symptom; light fixes the cause.

Trimming Protocol

1. Cut at desired height (leave 6+ inches base).
2. Wear gloves; watch for white sap (Euphorbia = toxic).
3. Callus top 2–3 weeks; root in dry gritty mix.
4. Base: keep dry, bright; will branch below cut.

Long-Term Fix

• Move to brightest window + grow light (12–14 hrs).
• New growth will be compact and strong.
• Rotate weekly for symmetry.
