This is how he gets through the winter safely

Oleander is only partially hardy

The flowering shrub is only partially hardy, i. H. he can tolerate a maximum (and also only for a short time) to at most minus five degrees Celsius. However, even this low temperature can cause the oleander to freeze to death - a single night with slightly frosty temperatures is enough. For this reason, the plant should if possible overwinter under cold house conditions, ergo cool (but frost-free) at around five degrees Celsius and bright. If necessary, the shrub can survive the winter with little or even no light - for example in the basement or in a garage.

It's not enough to wrap up winter-proof

Simply pack oleander for winterization and leave it outside unfortunately not enough. This strategy might be successful in mild winters, but one frosty night will ruin any effort. Therefore, always keep an eye on the weather forecast and, if in doubt, move the oleander to its winter quarters. Until then, however, he can stay outdoors, wrapped up as warmly as possible. Place the pot on a thick styrofoam or wooden base and wrap it with bubble wrap. You wrap the shrub yourself in gardening fleece. Alternatively, you can sink the pot into the ground and pile the oleander like a rose.

Put in late, clear out early

In principle, oleanders should be cleared into winter quarters as late as possible and taken outside again as early as possible. In this way, the plant survives the winter better, because most plants look quite worn out after the winter break and need a while until they have recovered. A pruning is then often unavoidable, which can be problematic with oleanders in terms of flowering - after all, the shrub mainly flowers on biennial shoots.
