In order for your oleander to survive the winter unscathed, the nerium must hibernate in a cool room. Read here what preparations are necessary.
Oleander is not hardy
What temperatures can oleanders tolerate?
The oleander tolerates light frost, down to minus 5 degrees Celsius, without damage.
Like most plants or container plants from the Mediterranean, the beautiful oleander (Nerium oleander) can withstand a little frost. However, the oleander is not hardy, so you should bring it indoors in winter. And here some make a big mistake. Because they place the oleander in the living room or in the heated conservatory. There are temperatures of around 20 or 25 degrees. And that is harmful to oleanders in winter.
What problems can arise?
At temperatures above 15 degrees, scale insects can occur, which damage the plant. But that's not all. Because everyone knows that from time to time you forget to water the plants. However, if the oleander is kept too dry, another pest can spread - the spider mite. Therefore, you should consider the following tips in winter so that your oleander can survive them well.
Wintering oleanders properly - step by step
- Check whether your Nerium is not already infected by pests.
- Has weed spread in the bucket? Remove it before wintering.
- Choose a bright, cool location.
- If your oleander is to spend the winter in the basement or another dark room, it must not be too warm.
- Temperatures between just above zero and below 15 degrees are optimal - the best is 2-10 degrees Celsius.
- Ventilate the winter quarters regularly.
- The oleander only needs to be watered a little in winter, so that the root ball does not dry out.
Nerium oleander can up to three meters high grow and also go very wide. If you have such a specimen, it is advisable to cut the oleander before moving to the winter quarters. However, if there is enough space to spend the winter, postpone this measure until the following spring.
