DETAILS

Care Instructions
Cassia fistula requires bright, direct sunlight for optimal growth. It thrives in warm temperatures and moderate humidity. Water the plant when the soil is almost completely dry, but avoid waterlogging. The tree prefers a seasonally dry tropical climate and can tolerate drought conditions.
Soil
The golden shower tree prefers well-draining loamy soil. It can tolerate a range of soil types but performs best in soil that is not too heavy or waterlogged. Ensure the soil has good drainage to prevent root rot.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season to promote healthy growth and flowering. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
Repotting
Repot young trees every 2-3 years to accommodate their growing root system. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repotting is best done in the early spring before the growing season begins.
Propagation
Cassia fistula can be propagated from seeds or cuttings. Seeds should be soaked in water for 24 hours before planting to improve germination. Cuttings can be taken from semi-hardwood branches and rooted in a well-draining soil mix. Propagation is best done in the spring or early summer.
Pruning
Prune the tree during the dormant season to remove dead or diseased branches and to shape the tree. Regular pruning helps maintain the tree's structure and encourages healthy growth. Avoid heavy pruning, as this can stress the tree.
Toxicity
Cassia fistula is toxic to pets and humans if ingested. The seeds and pods contain compounds that can cause nausea, vomiting, and diarrhea. Handle the plant with care and keep it out of reach of children and pets.
Additional
Cassia fistula is a popular ornamental tree due to its striking yellow flowers. It is also used in traditional medicine for its laxative properties. The tree can attract pollinators such as bees and butterflies, making it a valuable addition to a garden.
