Close

Cyathea dealbata, or the Silver Tree Fern, is a small tree native to New Zealand, typically growing to 10-20 ft in height. It is the country's national symbol and makes a majestic addition to any garden. It requires full sun or semi-shade, and regular watering to maintain its ornamental foliage. The fronds are typically 10 ft meters long, with lush and silver colored undersides.

If growing in cold regions, the fern should preferably be grown in a pot and brought indoors during the winter. In USDA zones 8-11, the tree fern can thrive outdoors year-round, with regular watering and protection from snow or frost. When planting, prepare a hole that is big enough to hold the root ball. The tree should be planted at the same level as it was in its pot, and the soil should be kept evenly moist until the tree is established.

To boost growth, fertilize the fern with a balanced fertilizer every three months during the growing season. Pruning is not usually required for proper growth, but if you want to shape the fern, the shoots that appear from the crown should be cut off. When it's time to prune the fronds, only the oldest and most damaged should be removed to avoid stress on the tree.

The Silver Tree Fern is a beautiful addition to any garden, requiring little maintenance and providing a unique and beautiful look. With proper care and protection from cold climates, you can enjoy its lush and vibrant foliage for many years to come.
