DETAILS

Care Instructions
Haworthia retusa is relatively easy to care for. It prefers bright, indirect light and moderate temperatures. Water the plant sparingly, allowing the soil to dry out almost completely between waterings. It thrives in low to moderate humidity and does not require frequent watering. Ensure the plant is kept in a well-ventilated area to prevent rot.
Soil
Haworthia retusa prefers well-draining soil, such as a sandy or cactus mix. Good drainage is essential to prevent root rot. A mix of sand, perlite, and a small amount of organic matter works well. Avoid heavy, clay-based soils that retain moisture.
Fertilizer
Fertilize Haworthia retusa sparingly, using a balanced fertilizer with a nutrient composition of 2-7-7. Apply the fertilizer during the growing season, typically in spring and summer, at half the recommended strength. Avoid fertilizing during the plant's dormancy period.
Repotting
Repot Haworthia retusa every 2-3 years or when it outgrows its current pot. Choose a pot that is slightly larger than the current one and has good drainage. Gently remove the plant from its old pot, shake off excess soil, and place it in the new pot with fresh, well-draining soil.
Propagation
Haworthia retusa can be propagated through offsets or leaf cuttings. The best time to propagate is during the growing season. For offsets, gently separate them from the mother plant and plant them in their own pots. For leaf cuttings, allow the cut end to callous over for a few days before planting in well-draining soil.
Pruning
Pruning is not typically required for Haworthia retusa. However, you can remove any dead or damaged leaves to maintain the plant's appearance. Use clean, sharp scissors or pruning shears to make clean cuts.
Toxicity
Haworthia retusa is non-toxic to pets and humans. It is a safe choice for households with animals and children. However, it is always best to prevent pets from chewing on plants to avoid any potential digestive issues.
Additional
Haworthia retusa is a resilient plant that can tolerate some neglect, making it an excellent choice for beginners. Ensure it receives adequate light and avoid overwatering to keep it healthy. During its dormancy period in winter, reduce watering and allow the plant to rest.
