Growing Cyathea cooperi can be an enjoyable and rewarding experience that adds a unique beauty to one's outdoor space. Adequate moisture is key to the tree fern success, so it should be planted in moist, rich soils with good drainage. It prefers full sun, but some semi-shade is also acceptable. For potted specimens, soil should be renewed yearly, and the potting mix should be kept consistently and slightly moist to prevent the fern from drying out. To ensure the tree fern continued health and growth, it should be fertilized several times a year, but with low nitrogen fertilizers to avoid spurring overly leafy growth.

For those in colder climates, Cyathea cooperi can be kept successfully in a pot and placed in a cool, sheltered corner for the winter. When nighttime temperatures drop below 30°F, the pot should be covered with plastic and a light insulating layer of mulch or hay. During the winter, water should be kept to a minimum, and then increased slightly as spring approaches and temperatures begin to rise. As long as the tree is not exposed to severe cold for an extended period of time, it should survive and thrive, making it a beautiful addition to any outdoor space.
