What is the plant

Australian tree fern is more tree than fern. Usually, when we think of ferns, we picture plants such as painted ferns (Athyrium niponicum), which achieve a mature height of just 18 inches. But in its native habitat, the Australian tree fern grows to 40 feet or more. This tropical plant is easily too large for most indoor growing situations except for the largest of greenhouses.

How to Care for the Plant

Water
Keep the soil moist at all times. Australian tree ferns are not drought tolerant and need weekly watering, with high levels of moisture or humidity in dry weather. However, avoid watering the crown directly as this can cause rot. The less shade they get, the more water that they will need.
Fertilizer
During the growing season, feed with controlled-release fertilizer or biweekly with weak liquid fertilizer. Larger specimens are heavy feeders.
Sunlight
Although these are shade-loving plants in general, they can also thrive in medium shade to full sun locations, whether exposed or sheltered.
