Cyathea cooperi, also known as Sphaeropteris cooperi) Characterized by lacy, feathery fronds, and a hair-like, scale-covered trunk, the fast-growing Australian tree fern can bring an exotic touch to any garden. It's best planted in the early spring and prefers warm temperatures and plentiful sunlight year-round.
A tree fern can grow up to 25 feet tall.
Although Australian tree ferns are shade-loving plants in general, they can also thrive in partial sun or full sun locations where they get over six hours of light a day. Keep in mind, the more direct light the plant receives, the more likely it is that you'll need to increase your watering cadence.
Australian tree ferns can tolerate a variety of soil conditions including sand, loam, and clay. That being said, they will thrive best in a moist, loamy mixture that is rich but well-draining with a neutral to acidic pH level. It's also recommended that you add a layer of mulch around the tree, which will add more nutrients to the soil and act as a barrier to seal in moisture (particularly during very hot weather).
Keep the soil moist at all times. Australian tree ferns are not drought-tolerant and need weekly watering, with especially high levels of moisture or humidity in dry weather. Avoid watering the crown directly as this can cause rot—instead, water the trunk and ensure it's consistently moist.
