Care tips

This species prefers full sun exposure and well-drained soils, even poor or sandy ones, as it is very adaptable and drought-tolerant once established. Watering should be moderate, allowing the substrate to dry out completely between waterings to prevent waterlogging. A common mistake is planting it in overly rich or excessively moist soils, which can lead to leggy growth and reduced vigor. It does not require regular fertilization and benefits from pruning to maintain a compact shape if desired.
