Growing, Harvesting and Storage

Erythrina variegata grows best in well-drained, loamy soil that is rich in organic matter, with a pH range of 6.

0 to 7. 5, and requires full sun to partial shade for optimal growth. It thrives in warm, tropical climates and requires regular watering during the growing season, though it is relatively drought-tolerant once established. Regular pruning is essential to maintain its shape, promote flowering, and prevent disease, while mulching helps retain soil moisture and suppress weeds. The plant is typically harvested when its pods turn from green to a deep yellow or brown, usually 6 to 8 months after planting, by cutting the branches or pods with pruning shears to avoid damaging the plant.

For storage, the harvested pods should be dried in a well-ventilated area or under the sun to preserve their potency, then stored in airtight containers in a cool, dry place or refrigerated to extend their shelf life.
