How do you take care of cactus?
This depends on the type, but if it is a round (ball) cactus or a tall (columnar) cactus, you would water it every 2 to 3 weeks. If it is a Christmas cactus, an Easter cactus or an Epiphyllum, water it every 2 weeks. Both types like bright light. Do not put them in direct sunlight. A warm, south facing window is good for the ball and columnar cactus. A slightly cooler room is better for the other types.
