Haworthia cymbiformis, also known as the Cathedral Window Haworthia, is a succulent plant that requires minimal care. Here are some care tips:

1. Light: Place your Haworthia cymbiformis in bright, indirect sunlight. Avoid exposing it to direct sunlight, as it can scorch the leaves.
2. Watering: Allow the soil to dry out completely between waterings. Water the plant thoroughly, but make sure the excess water drains away to prevent root rot.
3. Soil: Use a well-draining cactus or succulent soil mix. It should be gritty and provide good drainage.
4. Temperature and Humidity: Haworthia cymbiformis prefers average room temperatures between 65-80°F (18-26°C) and moderate humidity levels.
5. Propagation: You can propagate Haworthia cymbiformis by separating offsets from the parent plant or by leaf cuttings.
6. Fertilizer: Feed the plant with a diluted, balanced succulent fertilizer once or twice during the growing season.

Remember, each plant is unique, so observe your Haworthia cymbiformis and adjust its care accordingly.
