8" hanging pot
Use a pot with drainage. Allow soil to dry out a bit between watering. Water when the top 1-2 inches of soil dries out.
Bright, indirect light. If it gets enough light, ric rac cactus may produce large stunning blooms in early spring (pink and white orchid-like flowers).
This epiphyte can make a good hanging plant, spilling over the sides as it grows.
Aerial roots may appear along the stem, which epiphytes use to attach themselves to trees and other surfaces in the wild.
