Coral Cactus (Euphorbia lactea 'Cristata') Care: Glued Rocks, Watering, Repotting

A reader’s new coral cactus (gift, 5 days old) came in a 3″ plastic pot inside a ceramic cachepot. The soil surface has glued rocks. The care tag (for a cactus garden) says water 2–3 times a week until “established” and mentions blooming. The plant has brown, dead-looking tissue along its wavy crests.

Immediate Fixes

1. Remove glued rocks: Pry them off with a screwdriver. They’re for shipping only. Replace with loose river rock if desired.
2. Do not repot: Disturbing roots makes it hard to re-stabilize. If the cachepot is disliked, slip the plastic pot into a new decorative pot of the same size.
3. Water correctly: This is a succulent. Water only when soil is bone-dry. Insert a bamboo skewer to the bottom; if moist halfway up, wait. Water 1–2 times a week max. Empty saucer after 1 hour.

About the Brown Tissue

The brown material along the crests is often natural aging or minor sunburn, not disease. The plant is grown for its fascinating crested form, not flowers (rare indoors).
