Need a lot of sunlight (2000-5000 liumen). Streches if lack of light. Needs well draining soil (cactus soil - one part perlite, one part sand and one part compost. Also add coal to prevent rot). Fertilising only in the growth period ( summer, spring, early outumn). Watering periods are very important: water well and let it completely dry. It's better to underwater, than overwater. If underwatered it can be easily reanimated with water, but if overwatered - it will rot and nothing will save it. It can't be propagated with leaf, only with babies, that grow near to the motherplant, just like aloe.
