Do not water on a fixed day. Test the soil first. Read the soil check guide.

Use a cactus mix with extra perlite or sand. The mix must drain fast.

The white sap can irritate skin and eyes. Wear gloves and wash your hands after you touch cut stems.
The plant drops leaves in cold air, in drafts or after a move. New leaves grow back in time.
Few flowers mean too little light. Move it to a sunnier place.
