Dicksonia antarctica care tips

Plant in a cool, shaded spot with moist, free-draining soil rich in organic matter. Keep the trunk and root zone consistently damp, especially during dry spells, and water the trunk directly to promote healthy growth. Mulch yearly to conserve moisture and suppress weeds. Protect from harsh sun and strong winds to prevent damage to fronds. Remove old or damaged fronds at the base as needed. This fern is hardy and low-maintenance once established.

Tree size, spacing, and growth rate

Dicksonia antarctica can grow up to 4 to 6 metres tall with a canopy spread of 2 to 3 metres. It has a slow growth rate, typically gaining 5 to 10 centimetres of trunk height per year. For best results, space plants 1.5 to 2 metres apart to allow room for the fronds to spread naturally and create a layered, forest like effect.
