How to care for Christmas Cactus
Schlumbergera truncata
Written by Benjamin — a plant parent, not a search engine.
How often should I water Christmas Cactus, and what light does it need?
Christmas cacti are pet-safe and reward easy care with a spectacular winter bloom. Water when the top inch dries and give it cool nights in fall to set buds. Water it every 7–10 days while it is growing and every 10–14 days in winter, always checking the soil first. Give it medium light. It is non-toxic to cats and dogs — more detail below.

The short version
The one-sentence rule
Water when the top inch dries. To trigger winter blooms, give it 6 weeks of longer nights in fall and keep it cool.
Light, made concrete
What medium light actually means
Medium light — a meter or two from a north or east window, bright but no harsh sun. The sweet spot for most common houseplants.
Pet safety
Is Christmas Cactus toxic to cats or dogs?
No — Non-toxic to cats and dogs. It is not considered toxic to pets, but any plant can upset a sensitive stomach, so it is still not a salad bar.
