If possible, only tree species that are sufficiently hardy for the respective region should be planted in the garden. If this is not the case, these trees should be cultivated in pots and housed according to their needs over the winter months - for example in a cold room or, for exotic trees, in warmer temperatures.

Winter protection for hardy trees
But even hardy trees benefit from certain protective measures that can be used, for example, to minimize or even prevent damage from dry frost. Shallow-rooted plants are also endangered in cold, but snow-free winters, because their roots can freeze. You can protect the latter by spreading a thick layer of mulch material on the tree disc or covering it with fir or spruce branches. The trunk and branches can be protected from frost damage with a lime coat. This measure is particularly recommended for fruit trees in exposed, very sunny locations.
tips
Trees in pots, even if they are hardy, need good winter protection. Place the pot on an insulating base (wood or styrofoam), push it against a warm wall and, if necessary, wrap the tree in a fleece to protect against the cold.
