How to keep Exostema Caribaeum.
Light
Caribbean princewood comes from open habitats, like sunny meadows and the edges of forests, where light is plentiful. It does best in Full Sun but can withstand Partial Sun, showing good adaptability to different light conditions.
Temperature
Caribbean princewood comes from tropical areas where the climate is generally warm and humid. Therefore, it is suited to high temperatures and humidity. It dislikes sudden temperature changes and prefers a consistent thermal environment, so avoiding temperature fluctuations indoors is important. It typically cannot tolerate cold conditions and needs warmer temperatures to grow. If the surrounding temperature falls too low, the plant may stop growing or even die.
Fertilizer
The best time to fertilize a Caribbean princewood is in early spring, as it comes out of dormancy. This encourages overall growth and supports flower development. Fertilizing improves the foliage, stems, and branches, and encourages large, vibrant, long-lasting flowers. It also helps move nutrients from the roots to the flowers and enhances the plant's health and resistance to disease.
