WHAT IS HAWORTHIA?
Haworthia is a genus of small succulent plants that are indigenous to Southern Africa. Together with aloes, Haworthia plants are in the subfamily of Asphodeloideae. They usually have firm, tough, and fleshy leaves in dark green color. However, some species can be softer and contain leaf windows with translucent panels which facilitate the photosynthesis process. Most Haworthia plants grow small rosettes of leaves from 4 cm (2 in) to 20 cm (8 in) and they tend to have small white flowers in summer.
Temperature
Haworthia succulents prefer warm weather. Temperatures in the spring and fall are optimal for them. They can survive cool winter but will not do well under 40°F (4°C).
Sun exposure
Bright, filtered light and ample airflow are recommended. The lack of sunlight can cause Haworthias to etiolate and lose their vibrant colors. Newly acquired tender plants or plants that have been grown indoors need to be gradually introduced to sunlight to avoid fatal sunburn.
Water
Water thoroughly only when the soil is dry to the touch (about every 2 weeks). Never let your succulents sit in water and do NOT water on the leaves. Don't forget to learn how to water your succulents the right way.
You can water more often if you live in areas with hot weather because your soil will dry out faster. Reduce watering in winter because the succulent can lose its roots if the soil stays cold and wet for an extended amount of time.
Propagation and Soil
You can propagate Haworthia plants by using a sharp knife to separate the offsets from the mother plant. Try cutting as close to the mother plant as possible to make sure that the offset has some roots attached to it. Let the offsets callous over for a day or two to prevent root rot and pot them in some succulent soil mix. It’s important to provide porous soil with adequate drainage. Check out the perfect ratio for potting soil mix here.
Fertilizer
Feed sparingly with a weak fertilizer solution to promote plant growth. You can use an all-purpose fertilizer diluted to 50% of the recommended dose to feed your Haworthia once at the beginning of the growing season (in the spring or fall).
