Care Guide
Amborella trichopoda is a relatively easy plant to care for. It prefers well-drained soil that is rich in organic matter, and it should be watered regularly to keep the soil moist but not waterlogged. It does not require frequent fertilization, but a slow-release fertilizer can be applied in the spring.Amborella trichopoda prefers partial shade to full sun, and it is hardy in USDA zones 10-11. It can be grown indoors in a brightly lit location, but it will require regular pruning to keep it from outgrowing its container.
