Although the oleander requires little attention in terms of general care, it does require species-appropriate winter protection. When the impressive blooms open the following spring, you'll know your effort was worth it. Read on this page how to protect the bush from the cold in winter.

Oleander is sensitive to frost but can survive mild winters outside

Bring oleanders into the house

The oleander comes from the warm Mediterranean countries and feels most comfortable in the fresh air in bright sunshine. Since the plant tolerates slightly below zero for a short time, you should delay the winter protection as long as possible. An exact recommendation cannot be given. It is best to use the outside temperature as a guide, which should also be used as a factor for the end of the winter period.

Demands on the winter quarters

  • bright
  • cool (best 5°C to 10°C)
  • dry
  • sheltered from the wind

Recommended locations in winter

  • cool stairwells
  • unheated conservatories
  • special winter tents
  • greenhouses

tips

The oleander makes special demands on the light conditions during the winter. Depending on the temperature, you should adjust the brightness. As a result, the colder it is, the darker the location can be. In general, the oleander should not be illuminated for more than ten hours a day, unless the temperatures rise well above 10°C. If the winter quarters do not allow for these conditions due to the early setting sun, artificial lighting will help.

Oleanders overwinter outside

If the weather forecast announces severe frost, you should wrap the oleander in a fleece, as is usual with other plants. We do not recommend using a film, as mold quickly forms. However, a fleece may only remain in place for a few days. The lack of light would otherwise cause the shrub to die. In any case, you should insulate the pot. Place the oleander in a wind-protected, covered place, preferably on a house wall.

Further care measures in winter

  • Check the condition of the oleander daily.
  • Only water and fertilize the shrub when temperatures rise briefly.
  • At the end of the hibernation, cut back the branches and repot the oleander.

Note: Yellow leaves are a clear sign that the substrate is too wet.
