How to Grow and Care

These succulents are not considered difficult houseplants to grow. If you can keep a pot of Aloe alive on a windowsill, chances are you can do the same with a dish of Haworthia. As with all succulents, the most dangerous situation is too much water. They should never be allowed to sit in water under any circumstances. At the same time, these decorative, little plants can be grown in interesting containers such as tea cups and even miniature baby shoes. If you're given a Haworthia in such a container, make sure the container had adequate drainage.

Haworthias are small, usually remaining between 3  and 5 inches (7.5 cm and 12.5 cm)  in height, and relatively slow-growing. They are often grown in small clusters in wide, shallow dishes. Over time, clusters will naturally enlarge as the mother plant sends off small plantlets. When the cluster has outgrown its dish, repot in the spring or early summer into a new wide and shallow dish with fresh potting soil. This is also the time to take offsets for propagation.

Haworthia cymbiformis is native to South Africa (Port Elizabeth to East London in the Eastern Cape Province, on rocky slopes along rivers and streams).
