How to Grow Haworthia Indoors

The Spruce

Haworthia is a large genus of small succulent plants, most of them native to South Africa. They are generally lumped under the common name Hawthoria, though different species may carry other common names. Haworthias are delightful little succulents that make very attractive small houseplants. Potted plants are often moved outdoors for the summer months, and in regions without frost, they are sometimes grown as garden plants.

These small, low-growing plants form rosettes of fleshy green leaves that are generously covered with white, pearly warts or bands, giving them a distinctive appearance. Generally easy to grow, the same best practices that yield healthy aloe and echeveria plants will also produce beautiful Haworthia plants. Like other succulents, these plants appreciate bright light and adequate moisture in the summer, and relatively drier conditions in the winter. Outdoors, these plants generally do best in sheltered locations rather than in full sunlight. Avoid overwatering, but don’t let them dry out too much.

Hawthoria plants are generally purchased as potted specimens. Like many succulents, they are fairly slow-growing plants and will normally remain less than 6 inches tall. A few species, though, can grow up to 20 inches tall.

Watch Now: How to Grow and Care for a Haworthia Plant

Haworthia Care

Haworthia is not considered a difficult houseplant to grow—if you can keep a pot of aloe alive on a windowsill, chances are you can do the same with Haworthia. As with all succulents, the most dangerous situation is too much water, since they should never be allowed to sit in water under any circumstances.

At the same time, these little decorative plants can be grown in interesting containers such as teacups and even miniature baby shoes. If you've given a Haworthia in such a container, make sure the container had adequate drainage. If it doesn't, it might be a good idea to pop the plant out of its container and add a layer of gravel to the bottom to reduce the wicking action of the soil above. Finally, look out for sunburned spots on your plants.

Haworthia species like bright light, but not direct sunlight. In their native environment, they are often found in the shade of a rock or other object. They do best in a room with a window facing east or west to provide bright light for a few hours a day. White or yellow leaves usually signify too much sun. If the plant isn't getting enough light, its green color will fade. If you move your indoor Haworthia outdoors for the warmer months, avoid too much direct sunlight or it may get a sunburn.


Use a cactus mix or very fast-draining potting soil. Many growers warn that mixing potting soil with sand clogs up the pores so the soil doesn't drain as well, so sand should be avoided. Instead, mix with perlite, aquarium gravel, or pumice.


Water evenly and generously in the summer, letting the soil media dry out between waterings. In the winter, reduce watering to every other month. Never allow water to collect in the rosette.

Temperature and Humidity

Haworthia species like warmer temperatures in the summer but cool in the winter (down to 50 degrees Fahrenheit). They can get a freezing injury at 40 degrees Fahrenheit. This plant doesn't need any humidity. What it does require is good ventilation, especially at night when they take in carbon dioxide for photosynthesis. You might use a fan to keep air circulating so your Haworthia can breathe.


Fertilize during the summer growing season with a cactus fertilizer. Don't feed during the winter.

Hawthoria Varietes

There are more than 100 species of Haworthia, but their classification can be complex. The main difference between the common species is the size of the leaves and the orientation of the white markings on the leaves. In general, the best advice is to buy the most attractive variety based on leaf form and markings, as they all have similar cultural requirements. Look for these:

  • H. margaritifera has warty white projections on the leaves.
  • H. fasciata features horizontal white stripes and is sometimes called the zebra Haworthia.
  • H. bolusii have "tufted" edges to the leaves.
  • H. attenuata features long pointed green leaves.

Propagating Hawthoria

Haworthia plants can be propagated at repotting time using offsets from the mother plant. When taking offsets, use a sharp knife or snippers and cut as close to the mother stem as possible to include as many roots as possible, then allow the offset to dry briefly before repotting it (similar to cuttings from other succulents).

Pot the offsets in a small pot, using the same type of soil used for the mother plant. Put the planted offset in a warm, bright spot, and make sure to adequately water.

For a plant that doesn't form offsets, you can also propagate with a leaf cutting. Take a single healthy leaf with some stem tissue attached. Allow the leaf to callous over for several days, then plant the bottom tip of the leaf in a container filled with a well-draining succulent mix. Water moderately whenever the soil mix is dry. Gradually, one or more new plants will begin to grow from the leaf.

Potting and Repotting

Haworthias are small (usually remaining between 3 and 5 inches 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 container (every four to five years) repot in the spring or early summer into a new wide and shallow container with fresh potting soil. Even when a larger pot is not needed, these plants may benefit from repotting in the same pot with fresh soil. This is also the time to take offsets for propagation.

Common Pests/Diseases

Haworthias are free of most pests, with one exception: mealybugs. These pests can be controlled by simple physical removal or with an insecticidal spray. If soil is kept too moist, you may also have problems with fungus gnats.

The only disease common for Hawthoria is root rot, which can occur if the plant is overwatered.
