Which species of tree fern are hardy?
The tree fern looks majestic.With its long fronds, its brown trunk and its tropical-looking character, it creates atmospheric accents. But what will become of him in the winter? Does he need frost protection?
In the tropics there is no frost for tree ferns
Most tree ferns are originally from tropical regions. There they do not have to withstand frost. For this reason, they are not designed to survive the winter of Central Europe with snow, frost and ice.

The frost periods should not last long. In principle, mild conditions are ideal in Germany, such as the Lake Constance region and winegrowing areas in the Rhineland Palatinate.
