Weed periodically in a 1-m circle around the plants. Sealing the cuts with paraffin, plastic, mud or other material can increase survival rates. Cuttings begin producing fruit about 18 months after planting. Large nodules form in the upper soil surface and decrease in size with increasing soil depth. Limitations Erythrina edulis does not tolerate long periods of drought, especially during early stages of establishment.
Stem borers damage terminal shoots and cause lateral branching.
Future research needs The large differences observed in seed size suggest the existence of genetic variation. Rangewide provenance collection and testing is needed to determine differences in fruit yield, biomass production, nutrient content and adaptability. Research would also be useful on improved methods to increase seed viability. Symbiotic relationships need to be explored and quantified. Finally, traditional agroforestry uses of E. edulis and pest and ,disease management need further documentation.
