There are several types of growing care for Erythrina humeana, especially in cold areas. When planting, ensure that the location is sheltered from extreme winds. A sunny, well-draining and moist location is best. When grown in a pot, it is important to choose one that is slightly larger than the root system and filled with soil that is rich in organic matter.

In cold climates, it is highly recommended to bring potted plants inside for the winter or provide additional insulation for protection.
