The Japanese maple originally comes from the cold mountain regions of Japan, where it is particularly widespread on the islands of Honshu and Hokkaido. The climate there is not entirely dissimilar to that of Central Europe: the summers are quite short and warm, while the winters are long and cold. Ergo, the Japanese maple is by nature already used to winter climatic adversity and is therefore considered to be quite hardy even in our latitudes.

Protect roots in buckets
While planted Japanese maples usually do not extra winter protection, you should protect tub specimens very well. Since their roots are not in the solid soil, but only through a thin substrate layer and that Material of the planter are shielded from the cold, they are quite vulnerable and threaten and cold winters too freeze to death. However, this threat can be counteracted by
- the bucket is placed in a protected and bright location
- For example, a house wall that emits heat is ideal
- avoiding drafts
- the bucket on an insulating surface (e.g. B. Styrofoam)
- and with a fleece or similar ä. is wrapped.
- the substrate is covered with spruce branches.
In addition, Japanese maple should also be watered from time to time in winter, but only on frost-free days. If the substrate is frozen through due to frosty temperatures, the water does not reach the roots and can also damage them. You should therefore only water when it is comparatively mild and the weather is rather dry. Further maintenance measures are not to be observed in winter.
Tips
Japanese maples sprout comparatively early, whereby you should protect the delicate leaves from the threat of late frost in April and May, for example by means of a fleece cover.
