HOW TO WATER TREE FERNS
Tree ferns are among the most magnificent and resilient of all plant species and posses an architectural quality almost unique in nature.
Unfortunately it is the very fact of its uniqueness that causes concern when it comes to looking after them. Why, well it’s because - when purchased - tree ferns generally come without a root system, and look more like a detached elephant leg than anything else.
In the garden situation you would use either a hose or watering can fitted with a rose, watering the entire plant from top to bottom. While your tree fern may be bought without roots, once potted on these will be produced during the growing season.
If your tree fern is positioned in full sun it is likely to need watering most days, especially during the summer. If it is growing in the shade or semi-shade then you should be able to get away with watering every two to three days. Once the cooler temperatures of autumn arrive watering can be dropped off to perhaps once a week but you still do not want the truck or the crown to dry out. It is only over the winter period that the crown should just be kept on the damp side, but it may also require protection to stop the crown from fully freezing and damaging next seasons new growth.
If you have purchased your tree fern as just a cut trunk it is worth letting it soak in a bath of water for an hour or so before planting.
