Soil Type

Water: Native to warm regions, orchid tree needs moderate humidity and well-draining soil. Once established, it is drought-tolerant but prefers consistent moisture during growth, requiring watering every two weeks. As an outdoor ornamental, orchid tree thrives in various climates but needs adequate water during dry spells to ensure vibrant flowering.

Fertilize: For orchid tree, use a balanced N-P-K fertilizer quarterly during growth, semi-annually in dormancy. Follow manufacturer directions to avoid over-fertilization. Water thoroughly after application. Adjust fertilization as orchid tree matures, and always wear gloves and wash hands post-handling fertilizers.

Pruning: Orchid tree thrives with proper pruning in early spring, targeting dead or damaged wood and thinning crowded branches for airflow. This encourages healthy growth and blooms, shapes the plant naturally, and deters pests, ultimately enhancing its visual appeal and overall health.

Propagation: Orchid tree features unique butterfly-shaped leaves and vibrant flowers, thriving in warm environments. Propagate via semi-hardwood cuttings with leaf nodes, using rooting hormone in well-draining soil. Maintain consistent moisture and warmth for optimal rooting and growth.

Repotting: Orchid tree is a bush-like shrub needing repotting every 2-3 years, preferably in spring. Use a spacious container for root growth. Post-repotting, provide ample sunlight and moderate watering to promote recovery, essential for vibrant blooms and lush foliage.
