Propagation

Flowering in mangium is precocious. It starts to flower and produces seeds 18-20 months after planting. Pods can be collected from the trees in January-February under Kerala conditions, when the pods turn very dark-green to light-brown in colour. Seeds are extracted manually after sun-drying. Pods and seeds should not be left to dry in the sun for long. Store the seeds under dry and insect/rodent-free conditions. The number of seeds in one kg of pure seed varies among trees (mean: 125,000 seeds per kg).
