Silviculture Seed treatment . Erythrina edulis is easily propagated from seed or cuttings, but seedlings tend to root deeper and live longer than cuttings. Seed should be removed from pods immediately and stored in paper bags in a cool, dark place. They lose viability quickly and should be planted within eight days of harvesting. Viability can be extended up to 20 days by dipping seeds for a moment in molten paraffin so that a thin layer of paraffin coats the entire seed.
Larger seeds tend to produce more vigorous seedlings.
Plant seeds in 1-kg polyethylene bags with the convex side facing upwards and slightly exposed. Germination begins in 5 to10 days. Shade the seedlings in the nursery and reduce shade partially in the last two weeks before outplanting. At 60 days, seedlings may be planted out in holes 30 cm deep. Erythrina edulis can also be direct seeded.
