Care tips
It requires full sun for optimal growth, though it tolerates partial shade in very hot climates. Watering should be moderate, allowing the substrate to dry out completely between waterings, and reduced in winter to prevent root rot. It prefers a well-drained, sandy or rocky substrate with a neutral to slightly acidic pH. A common mistake to avoid is overwatering, which is the main cause of problems in cycads.
