Haworthia cymbiformis, commonly known as Boat-shaped Haworthia:
Light: Haworthia cymbiformis prefers bright, indirect light. It can tolerate some morning sun or filtered light but avoid prolonged exposure to intense, direct sunlight, especially in hot climates, as it can lead to leaf burn.
Watering: Water Haworthia cymbiformis thoroughly but infrequently. Allow the soil to dry out completely between waterings to prevent root rot. During the growing season (spring and summer), water when the top inch (2.5 cm) of soil feels dry. Reduce watering in winter when growth slows down, watering only when the soil is dry.
Soil: Plant Haworthia cymbiformis in a well-draining succulent or cactus mix. A sandy soil with good drainage is ideal. Ensure the pot has drainage holes to prevent waterlogging, which can cause root rot.
Temperature: Haworthia cymbiformis prefers moderate temperatures ranging from 65-80°F (18-27°C) during the active growing season. It can tolerate slightly cooler temperatures down to 50°F (10°C), but protect it from frost and freezing conditions.
Humidity: Average indoor humidity is generally suitable for Haworthia cymbiformis. It does not require high humidity levels and can tolerate dry air typical of indoor environments.
Fertilizing: Feed sparingly with a balanced, diluted fertilizer formulated for succulents once a month during the growing season (spring and summer). Refrain from fertilizing during fall and winter when the plant's growth slows down.
Propagation: Propagate Haworthia cymbiformis from offsets (pups) that develop around the base of mature plants. Gently separate the offsets from the main plant and replant them in a separate pot or area of the garden with well-draining soil. Allow cuttings to callus for a few days before planting to reduce the risk of rotting.
Pruning: Trim off any dead or dried leaves as needed to maintain the plant's appearance and health. Remove spent flower stalks to encourage new growth.
Pests and Problems: Monitor for common succulent pests such as aphids, mealybugs, or spider mites. Treat infestations promptly with insecticidal soap or neem oil. Ensure good air circulation around the plant to prevent fungal issues.
Potting and Repotting: Repot Haworthia cymbiformis every 2-3 years or when it outgrows its current container. Choose a slightly larger pot with drainage holes to accommodate the plant's root system.
Special Care Notes:
Haworthia cymbiformis is drought-tolerant but will thrive with consistent care. Avoid overwatering, as this can lead to root rot.
Place the plant in a location with good air circulation to prevent humidity-related issues and fungal diseases.
Protect Haworthia cymbiformis from extreme temperatures and sudden temperature fluctuations, which can stress the plant.
By following these care guidelines, you can help your Haworthia cymbiformis thrive and maintain its attractive, boat-shaped rosettes in your indoor or outdoor succulent collection.
