Soil Type

Water: Coral tree thrives in climates with dry and wet seasons, requiring watering every two weeks to accommodate its drought resilience. Typically grown outdoors for its ornamental value, coral tree benefits from seasonal rains that align with its natural moisture needs, suitable for comparable landscape conditions.

Fertilize: Fertilize coral tree with balanced nutrition semi-annually; spring boosts flowers, autumn strengthens roots. Apply gradually to prevent root burn, adjusting for plant maturity. Monthly liquid feedings during growing seasons support vigorous growth. Always water coral tree after fertilization for nutrient absorption.

Pruning: Renowned for vibrant red flowers, coral tree benefits from strategic early spring pruning to enhance growth. Key techniques include removing dead wood and thinning crowded areas for better air circulation. Proper cuts at nodes stimulate blooming, control size, and prevent structural issues, resulting in a vigorous plant.

Propagation: Coral tree is a leguminous tree noted for its striking flowers. Propagate coral tree by sowing fresh seeds, ideally soaked in warm water. Use well-draining soil, planting seeds at twice their diameter, and provide moisture. Protect seedlings from harsh conditions until ready for transplanting.

Repotting: Repot coral tree every 2-3 years in early spring, using a spacious container. Ensure well-draining soil and provide moderate water and full sun. Consistent aftercare, including staking if needed, supports coral tree's growth as a large, ornamental bush.
