Oleander is not hardy
Like so many Mediterranean plants, oleander is not frost-resistant and therefore not hardy. Light frost up to approx. minus five degrees Celsius is usually tolerated, but only for a very short time - the shrub quickly gets frost damage, which results in brown, dried up leaves and express urges. Let the oleander in late autumn or Stand quietly outside in mild winters, but provide it with protection against the cold at night (e.g. a Garden fleece) or, if the temperatures are to drop sharply, bring it to a cool, but frost-free room.

In principle, the oleander should stay outdoors as long as possible and only be moved to winter quarters when the temperatures drop below zero. How much frost an oleander can withstand cannot be determined by specific degrees, but depends on the individual plant. Some varieties of oleander
(for example, 'Papa Gambetta', 'Italia' or 'Lutein Plenum') are considered to be particularly frost-resistant, while others are significantly more sensitive to the cold. Older plants are also more robust than young ones. However, a frost-free wintering is advisable for each specimen if possible.Tips
In summer, on the other hand, it cannot be warm enough for the oleander, because it only shows its bloom when there is a lot of sun and warmth. If, on the other hand, it is cold and rainy, the hoped-for can be Bloom also just fail. In this case, move the oleander into a winter garden - if available - and use plant lamps to ensure sufficient brightness.
