For amborella, a genus with unique botanical importance, select a rich, well-draining soil and a partially shaded location mimicking its native understory habitat. Ensure consistent moisture without waterlogging. Start by loosening the soil to a depth of several inches and incorporate organic matter. Space the plants to allow for growth. After planting, water thoroughly and maintain soil moisture. For best success, acclimate plants to their outdoor environment and protect from extreme conditions. Specific needs may vary; research on individual species is advised.
