Cultivation and Propagation: They are amongst the easiest Haworthias to grow. On account of their easy cultivation these plants are fairly common in collections and are more tolerant of injudicious watering than the others. They must be repotted frequently, because every year a part of their roots die and then rots in the pot. They are very responsive to differing cultural conditions both as regards colour, length and shape of leaves, rate of growth and size of plant.
Watering Needs: Water regularly in the growing season, but avoid water-logging and let dry between watering, they should never dry out completely during the rest period.
Frost Tolerance: Hardy to -1 (-5)°C.
Propagation: Seeds or (usually) offsets.
Sun Exposure: It prefers locations with diffuse sunlight or light shade, it can tolerate shade. It proliferates rapidly and should be exposed to at least some direct sunlight to prevent bloating and excessive softening of the plants, but shelter from direct sun during the hottest hours! Plants can have more remarkable colour under stress and if more exposed to direct sunlight.
