Light watering
He doesn’t need much, just give him a good drink when the soil has almost completely dried out and don’t leave him sitting in water.
Medium light
He’ll do best in a spot that gets bright, indirect sunlight. Think away from the window in a sunny room.
Feeding
He’s a slow-grower, but you can give him a boost with a succulent-specific fertiliser once a month in spring and summer.
