Haworthias are small, slow-growing succulents that are native to South Africa. They are prized for their unique appearance, which can range from smooth and green to covered in white bumps or stripes. Haworthia plants are relatively easy to care for, making them a popular choice for indoor gardeners.
They are a rewarding plant to grow, and they will add a touch of unique beauty to your home.
Characteristics of Haworthias
Common characteristics of haworthia plants:
- Small size: Haworthias typically grow to be 3 to 6 inches tall and 3 to 5 inches wide.
- Succulent leaves: Haworthia leaves are fleshy and store water, helping the plant to survive in dry conditions.
- Variety of textures and colors: Haworthia leaves can be smooth, bumpy, or spiny, and they come in a wide range of colors, including green, white, and purple.
- Slow-growing: Haworthias are slow-growing plants, typically only adding a few inches in height each year.
Haworthia Care Guide
Haworthia plants are a rewarding succulent and relatively easy to care for. They’re low maintenance plants that look great on a windowsill, as long as they have the correct care requirements.
Haworthias need bright, indirect light to thrive. They can tolerate some direct sunlight, but too much can scorch their leaves. A south-facing window is ideal, but an east-facing window is also good. If you only have a north-facing window, you may need to supplement with a grow light.
They are drought-tolerant plants, so it is important to water haworthias deeply, but infrequently. Allow the soil to dry out completely between waterings. Overwatering is one of the most common mistakes made with haworthia care, and it can lead to root rot.
Haworthias need well-draining soil to prevent root rot. A commercial cactus and succulent potting mix is ideal. You can also make your own potting mix by combining equal parts potting soil, perlite, and sand.
As they are succulents, haworthias prefer warm temperatures, between 65 and 75 degrees Fahrenheit. They can tolerate cooler temperatures, but they may go dormant if the temperature drops below 50 degrees Fahrenheit.
These succulents do not need high humidity. Average household humidity is fine.
Haworthias do not need much fertilizer. A light feeding of a balanced liquid fertilizer every few months during the growing season is sufficient.
Since Haworthias have shallow root systems, there’s no need to repot often. Every two to three years is usually enough. When repotting, choose a pot that is only one size larger than the current pot.
How to Propagate Haworthia
Haworthias are easy to propagate from division or from leaf cuttings.
To Propagate by Division
Division is the easiest way to propagate haworthias. To do this, simply remove the offsets, which are the small plants that grow around the base of the mother plant. You can use a sharp knife to cut the offsets away from the mother plant, or you can simply pull them off. Once you have removed the offsets, pot them up in their own pots with well-draining potting mix.
To Propagate by Leaf Cuttings
To propagate haworthias from leaf cuttings, take a healthy leaf from the mother plant and cut it off with a sharp knife. Allow the cut end to dry for a few days, then plant it in well-draining potting mix. Keep the soil moist but not soggy, and the cutting should root within a few weeks.
Haworthia flowers are small and delicate, typically white, pink, or green in color. They are not particularly showy, but they add a touch of charm to these succulent plants. Haworthias typically bloom in the spring or summer, but they may also flower at other times of the year.
The flowers are arranged in a raceme, which is a type of inflorescence in which the flowers are arranged along an elongated axis. The flowers are unisexual, meaning that they have either male or female reproductive organs. Haworthias are pollinated by insects, such bees and flies.
Haworthia flowers are not essential for the plant’s survival, but they do play an important role in reproduction. The seeds produced by the flowers allow the plant to spread and colonize new areas
Common Issues with Haworthia
Haworthias are relatively low-maintenance succulents, but they can still experience some common issues. Here are a few of the most common problems with haworthia plants and their care solutions:
Overwatering is one of the most common causes of death in haworthias. The plant’s roots need to breathe and if the soil is too wet, the roots can rot. To avoid overwatering, allow the soil to dry out completely between waterings.
Root rot is a fungal disease that can kill haworthias. It is caused from overwatering, poor drainage, or a combination of both. Symptoms of root rot include yellowing leaves, wilting, and a soft, mushy base. If you suspect root rot, it is important to act quickly. Remove the plant from its pot and check the roots. If they are black and mushy, the plant is beyond saving. However, if there are still healthy roots, you can repot the plant into a new pot with fresh, well-draining soil.
Pests and Diseases
Haworthias are relatively resistant to pests and diseases. However, they can be susceptible to mealybugs and scale insects. If you see any pests, treat the plant with an insecticidal soap or neem oil.
Haworthias prefer bright, indirect light. However, if they are exposed to too much direct sunlight, their leaves can sunburn. Sunburn will appear as brown or red patches on the leaves. If you think your haworthia is getting too much sun, move it to a shadier location.
Not Enough Sun
While too much sun can be harmful, too little sun can also be a problem for haworthias. If your haworthia is not getting enough light, its leaves may become pale or etiolated. To prevent this, make sure your haworthia is getting at least 6 hours of bright light per day.
These are just a few of the most common problems that haworthias can experience. With proper care, you can avoid these problems and keep your haworthia plants healthy and happy.
Types of Haworthias
There are over 150 species of haworthia, each with its own unique appearance. Some of the most popular and interesting haworthia species include:
Haworthia cooperi: This is one of the most common haworthia species, known for its transparent, windowed leaves. These leaves allow light to reach the plant’s inner tissues, helping it to photosynthesize more efficiently.
Haworthia fasciata: This is another popular haworthia species that is known for its white stripes. These stripes are actually raised bumps on the surface of the leaves, and they give the plant a textured appearance.
Haworthia retusa: This species of haworthia has smooth, green leaves arranged in a tight rosette. The leaves are slightly spoon-shaped, and they give the plant a very compact appearance.
Haworthia truncata: This haworthia species has thick, fleshy leaves arranged in a spiral pattern. The leaves are also slightly keeled, which means there’s a ridge running down the center.
Haworthia emelyae: This haworthia species has long, thin leaves arranged in a loose rosette. The leaves are also slightly translucent, and they give the plant a very delicate appearance.
Haworthia limifolia: This species of haworthia has wide, flat leaves arranged in a fan shape. The leaves are also slightly wavy, and they give the plant a very lush appearance.
Haworthia mucronata: This haworthia species has small, pointed leaves that are arranged in a dense rosette. The leaves are also slightly hairy, and they give the plant a very spiky appearance.
Haworthia arachnoidea: This haworthia species has small, hairy leaves that give it a spider-web appearance. The leaves are also slightly translucent, and they give the plant a very delicate appearance.
Haworthia bolusii: This species has thick, fleshy leaves covered in long, white spines. The spines are very sharp, and they give the plant a very protective appearance.
With such a wide variety to choose from, you are sure to find a Haworthia that is perfect for your home.

Here are some additional tips when caring for haworthias:
- Haworthias are slow-growing plants, so don’t expect them to grow quickly.
- These succulents can tolerate neglect, so don’t worry if you forget to water them occasionally.
- They can be sensitive to sudden changes in temperature, so be sure to acclimate them to their new environment gradually.
- Haworthias are not toxic to humans or pets.
With proper care, haworthias can live for many years. They are a rewarding plant to grow, and they will add a touch of unique beauty to your home.
