Care tips

It prefers full sun to partial shade for optimal growth and more intense foliage colors. Although it tolerates periods of drought once established, it appreciates regular watering in hot, dry climates, allowing the substrate to dry slightly between waterings. Use a well-drained substrate, as waterlogging is its main enemy. Avoid over-fertilization, as it can promote weak growth and susceptibility to diseases.
