Do this when you get home
- Put it in the sunniest spot in the house
- Water only when the soil is bone-dry. Drier is safer than wetter.

- Left in the dark for a long time, it grows thin and long, and the color fades
- When you repot, wrap it in newspaper or thick gloves so you don't get stuck
Common questions
