Cyathea milnei, also known as Milne's tree fern or Alsophila milnei, is a species of tree fern native to New Zealand. The Cyathea milnei can grow into an impressive, tree-like plant.

Appearance (when the plant is mature):
Cyathea milnei is a large, impressive tree fern that can grow up to 10 meters high.
The trunk of this tree fern is straight and covered with dark fibers, giving it a robust appearance.
The leaves of Cyathea milnei are large, pinnate and deep green in color. They can reach a length of about 3 to 4 meters and form an elegant, fan-shaped crown.

This tree fern is mainly found in moist rainforests, along river banks and in other moist forest environments in New Zealand.
Cyathea milnei thrives in shady, moist areas and can be found in the North Island and parts of the South Island of New Zealand.

Cyathea milnei is a slow growing plant and can take decades to reach maturity.
Like many other tree ferns, it is an important element in the biodiversity of New Zealand's forests, where it provides refuge for several species.

Caring for Cyathea milnei, also known as Milne's tree fern, requires specific attention to its growing environment, as this tree fern is native to New Zealand and thrives in moist, shady conditions. Here are some important care tips:

Light and location:
Place the tree fern in the shade or partial shade, as direct sunlight can lead to leaf burns.
In nature, Cyathea milnei often grows under the canopy of other trees, so try to mimic this in your garden or indoor environment.

Temperature and climate:
Keep the ambient temperature moderate and stable. This tree fern thrives best at moderate temperatures and cannot withstand frost.

Cyathea milnei needs moist conditions. Make sure the soil is always moist, but not soaked. Water regularly to keep the soil moist.
Spray the leaves regularly with water to increase humidity.



Use a well-drained potting soil with plenty of organic matter. In nature, this tree fern grows in organic soils rich in humus.

Power supply:

Feed the tree fern with a balanced liquid fern fertilizer once a month during the growing season (spring and summer).

Protection against frost:

In areas with severe winters, protect the tree fern from frost by temporarily moving it to a sheltered location or covering the crown with a layer of insulation.


Remove dead or damaged leaves to maintain the plant's health and maintain a neat appearance.


Depending on the size of the tree fern and its growth rate, you may need to repot it every few years. Choose a pot large enough to allow for further growth.

The Cyathea milnei specimens of Plantje van Mandje are approximately 30 cm high.
