Watering. Water regularly during the first few years to establish roots, allowing the soil to dry out slightly between waterings. Once established, it is drought tolerant and requires less frequent watering.
Fertilizing. Feed young trees once a year in early spring with a balanced, slow-release fertilizer. Mature trees usually do not require fertilizing unless growth appears slow or leaves look pale.
Araucaria araucana is a hardy tree that prefers full sun and well-draining soil. It tolerates drought once established but benefits from occasional watering during dry spells. It grows slowly and requires minimal maintenance, though young trees need protection from frost and strong winds.
