Understanding Pleiospilos nelii:

 Light Requirements:

Pleiospilos nelii thrives in bright, indirect light. Place your plant near a south-facing window where it can receive ample sunlight without direct exposure to harsh midday sun. Insufficient light can lead to etiolation, while too much direct sunlight may cause sunburn.

Soil and Potting:

These succulents prefer well-draining soil. A cactus mix or a blend of potting soil with added perlite or sand works well. Ensure the pot has drainage holes to prevent waterlogging, which can lead to root rot.

Watering Routine:

Pleiospilos nelii is adapted to arid conditions and should be watered sparingly. Allow the soil to dry out completely between waterings. During the active growing season in spring and autumn, water more frequently, but reduce watering in winter when the plant is dormant. If you are in any doubt about when to water a moisture meter can help.

Temperature and Humidity:

Maintain a warm and dry environment for your Pleiospilos nelii. They thrive in temperatures between 70-80°F (21-27°C) during the day and around 50-60°F (10-16°C) at night. Keep humidity levels low to prevent fungal issues.

 Encouraging Flowering

Mimic Natural Conditions:

Pleiospilos nelii blooms in response to its natural habitat conditions. To encourage flowering, simulate a winter dormancy period by reducing both light and temperature during the winter months. This triggers the plant to produce flowers in spring.

Controlled Watering:

During the winter dormancy period, limit watering to the bare minimum. This mimics the dry conditions of its native habitat, signaling to the plant that it's time to flower.

Patience is Key:

Pleiospilos nelii is known for its slow growth, and flowering may take several years. Be patient and maintain consistent care practices to support overall plant health, increasing the chances of a spectacular bloom.


Feed your Pleiospilos nelii with a diluted, balanced succulent fertilizer during the growing season (spring and autumn). Avoid fertilizing during the Winter dormancy period.

Caring for Pleiospilos nelii is a rewarding experience, and with the right conditions and patience, you can enjoy the breathtaking beauty of its vibrant flowers. By understanding its natural habitat and mimicking those conditions, you'll create an environment that encourages healthy growth and stunning blooms from this unusual succulent.
