Care tips
It prefers full sun to partial shade and moist, well-drained soils, tolerating a variety of soil types, including poor ones. Regular watering is important during the first few years to establish the root system, especially during dry periods. Avoid excessively alkaline soils, as they can affect its development. A common mistake is planting it in confined spaces, as it can grow quite large.
