Light: Full sun is best, but will do fine in light shade as well. These are good plants for a south-facing exposure or unobstructed east- or west-facing window.
Water: Furcraea foetida are drought resistant due to their large root system: watering them infrequently (though more so during their bloom in summer and spring) will be fine. Be careful not to overwater. As with most succulents, standing water can be lethal.
Soil: the Well-draining succulent mix is crucial—too much water will kill these plants, and they should never be in water-logged soil or allowed to stand in a tray with water.
