Repotting Cactus: Normal Stem Corking, Surface Roots, and Pilosocereus ID

Normal Post-Repotting Observations

• Brown stem base: Corking (bark formation)—protective, not rot.
• Dark green spots on small offset: Normal pigmentation variation.
• Surface roots: Adaptation to catch brief rainfall; not a watering error.

Watering After Repotting

Wait 7–10 days before first water to allow root wounds to callus. Then water thoroughly, then dry completely.

Pilosocereus Identification

Columnar, blue-green stems, dense white wool/hair at areoles (especially flowering zone), nocturnal flowers. Common species: P. pachycladus, P. azureus. Check Desert-Tropicals for visual match.

Ongoing Care

• Bright light (acclimate to direct sun gradually).
• Water when dry; reduce in winter.
• Fertilize 2×/year at ½ strength.
