Avonia species thrive in well-draining soils, such as sandy or rocky substrates that mimic their native arid habitats. They require full sun to partial shade and should be watered sparingly, as they are susceptible to root rot if overwatered. To plant, prepare an area with appropriate soil, create a small hole for the root ball, and position the plant without burying it too deep. After planting, water lightly and maintain a consistent watering schedule based on dryness of the soil, not frequency. Understanding the individual needs of different avonia species is vital, as some may have unique requirements.
