Succulent plant Haworthia cooperi var. Dielsiana
Haworthia species like bright light but not exceptionally strong direct sunlight. In their native environment, they are often found in the slight shade of a rock or other object. They can tolerate direct morning sun, but harsh afternoon rays can burn their foliage. White, red, or yellow leaves usually signifies too much sun. But if a plant isn't getting enough light, its green color will fade. Indoors, haworthias do best near an east- or west-facing window.
These plants like a sandy or gravelly soil with excellent drainage. Use a cactus potting mix or another very fast-draining potting soil intended for container plants. To improve soil drainage, mix the soil with perlite, aquarium gravel, or pumice.
Water whenever the top inch of soil has dried out during the spring and summer months, but make sure the soil is never waterlogged. In the fall and winter, reduce watering to just enough to keep the leaves plump. Never allow water to collect in the rosette, as this can lead to rot.
Haworthia species like warm temperatures between 70 and 95 degrees Fahrenheit in the summer and cool temperatures down to 50 degrees Fahrenheit in the winter. They can be damaged when temperatures fall to 40 degrees Fahrenheit and lower. Humidity isn't an issue for this plant. What it does require is good ventilation, especially at night when it takes in carbon dioxide for photosynthesis.
Follow label instructions to fertilize haworthia during the spring and summer growing season with a cactus fertilizer. Don't feed during the fall and winter.
