Oleander is not hardy
In principle, older and therefore more robust oleanders can withstand temperatures of up to minus five degrees Celsius - but only for a very short time and under no circumstances in combination with ground frost and other hardships. In other words: The oleander, which is adapted to the mild Mediterranean climate, is neither winter nor frost hardy and, if you plant it out in the garden, would most likely not survive a typical German winter. It is therefore always recommended to keep the bush in a bucket so that the shrub can be transferred to winter quarters in good time. A dark overwintering - for example in a cellar - does not necessarily harm the plant, it should only be frost-free.

Hibernate oleanders outside in protected locations?
It is well known that the winters in Germany are not equally severe everywhere, so that planting out can be tried in some regions such as the German wine-growing regions. So if you live in the Rhine-Moselle area and the winters are rather mild in your area: give it a try. For such an attempt, however, it is better to choose an older, already hardened plant and pack it well, for example with gardening fleece and / or bubble wrap. Nor does it get terribly cold every winter, some of these seasons remain mild. In months like this, you don't necessarily have to store the oleander, you can leave it outside - as soon as the temperatures drop, however, it is important to react quickly and move the shrub to the cellar. Of course, this only workswhen grown in a tub.
Temporary planting out over the summer is possible
However, you can also plant your oleander temporarily - ie for a limited time - and with the planter in the garden. Only the plant pot should be removed so that the shrub is only in the ground in the plant pot. This pot usually has holes in the bottom so that the roots of the oleander can grow through and supply themselves with water from the earth. As soon as it gets too cold, the shrub can easily be dug up again and overwintered under cold house conditions.
Tips
Do not move your oleander into winter quarters too early: the longer the plant is outside, the more it hardens and also survives the months with little light. The shrub only needs to be cleared in frosty periods.
