The tree fern appears majestic. With its long fronds, its brown trunk and its tropical-looking character, it provides atmospheric accents. But what will become of him in winter? Does he need antifreeze?

Most tree fern varieties come from the tropics and are not hardy

There is no frost for tree ferns in the tropics

Most tree ferns originally come from tropical regions. They don't have to withstand frost there. For this reason, they are not made to survive the winter of Central Europe with snow, frost and ice.

These species tolerate sub-zero temperatures

But not all species have the same characteristics. There are a few subspecies of tree fern that can stay outside through the winter. These include, for example:

  • Australian tree fern
  • Tasmanian tree fern
  • New Zealand tree fern
  • crown fern
  • silver tree fern

While the first two tree fern species are frost hardy down to -10 °C, the other three only tolerate temperatures down to -7 °C or down to -4 °C in unprotected locations. The periods of frost should not last long. Mild locations in Germany, such as the Lake Constance region and wine-growing areas in Rhineland-Palatinate, are generally ideal.

Protect sensitive tree ferns in winter

Tree ferns, which are houseplants in the living room, for example, should be placed in an unheated room in winter. There they overwinter. Room temperatures between 5 and 10 °C are ideal for hibernation. These prevail, for example, in the conservatory. It is extremely important that the tree fern is not exposed to the winter sun.

Pots or tubs that were on the balcony should either be placed inside or protected in winter. If you decide to leave the pot outside, it should be covered with fleece and placed on a styrofoam block. It is also important to place it in a protected location such as against the wall of the house.

Outdoor tree ferns can quickly suffer frost damage in winter. Young plants in particular are at risk. If there is no other way and they have to be overwintered outside, they can be protected as follows:

  • Cut back fronds
  • Tie the remaining parts together with string
  • apply a thick layer of bark mulch over the root area
  • Cover the trunk with reed mats or straw mats
  • If necessary, cover the frond with fleece

tips and tricks

Don't forget to water in winter! On the other hand, fertilizing becomes secondary. A fertilization break in winter does not harm the tree fern.
