Can Cyathea dealbata grow in full sun?

Cyathea dealbata generally does not grow well in full sun, especially when young. It naturally thrives in shaded or partially shaded environments, like forest understories, where it is protected from direct, harsh sunlight. Full sun can scorch the delicate fronds, dry out the soil too quickly, and stress the plant. However, mature plants can tolerate brief periods of morning sun if they are well-watered and protected from hot afternoon sun. For best results, plant it in a sheltered, semi-shaded position with consistently moist soil.
