Cereus peruvianus Cutting Care: Rooting, Sun, and Fertilizer

Scott's 2-foot Cereus peruvianus cutting showed scale, no new growth after winter indoors, now outside in full sun at 85°F+.

Protocol

1. Water with Superthrive (half strength) for first few waterings.
2. No fertilizer until vigorous growth—then ½ recommended rate.
3. Partial shade initially—move to full sun only after new growth appears.
4. Do not rotate—keep same side facing south.

Scale Treatment

Soap spray is good; repeat weekly until gone.

Patience: rooting takes weeks.
