Clusia, commonly known as the autograph tree, is a tropical plant genus belonging to the family Clusiaceae. Characterised by its thick, glossy leaves and ability to thrive in a variety of conditions, Clusia species are often used as decorative plants in gardens and indoor settings. The name ‘autograph tree’ originates from the leaves' unique characteristic of easily retaining marks made by a sharp object, resembling autographs. Clusia plants are also known for their resilience and can tolerate drought, making them suitable for low-maintenance landscapes. Some species produce attractive flowers and edible fruit, further enhancing their appeal.

Light

Clusia plants thrive in bright, indirect light but can also tolerate low light conditions. Avoid direct sunlight, as this can scorch the leaves.

Watering

Water your Clusia when the top layer of soil feels dry to the touch. Ensure the pot has good drainage to prevent waterlogging, which can lead to root rot. During the growing season (spring and summer), increase watering frequency, while in the dormant season (autumn and winter), reduce it slightly.

Humidity

Clusia prefers moderate humidity levels but can adapt to average indoor conditions. To encourage growth, consider misting the leaves occasionally or placing a humidity tray with water beneath the plant.

Temperature

Ideal temperatures for Clusia range from 18°C to 24°C. Protect the plant from cold drafts and extreme temperature fluctuations.

Soil

Use a well-draining potting mix, ideally one that contains peat and perlite or sand. This promotes good aeration and drainage.

Fertilisation

Fertilise every 4-6 weeks during the growing season with a balanced, water-soluble fertiliser. Reduce fertilisation in autumn and winter.
