Oleander gets yellow leaves - causes and antidotes

Unsuitable location

Oleander loves a warm place in the sun, which should also be protected from the wind. The Mediterranean plant cannot stand wind, it turns yellow. A change of location is also problematic, for example when moving from winter to summer quarters. This should always be done carefully and in stages so that the plant can get used to it.

Nutritional deficiency

If a lot of leaves turn yellow in a short period of time, this can indicate a lack of nutrients. The oleander is one of the heavy eaters and therefore has to be fertilized regularly - especially if it is cultivated in the tub. In the case of insufficient fertilization, the yellow leaves are an indication of a deficiency, often of nitrogen and / or potassium. Fertilize oleanders at least once or even twice a week with a good flowering plant fertilizer during the growing season.

Lack of water

In its natural habitat, the oleander likes to grow on river banks that are flooded from time to time. So the plant is used to having wet feet frequently. Oleander needs a lot of water and is one of the few species that can tolerate waterlogging itself. If there is a lack of water, the leaves can turn yellow and are eventually thrown off.

Warm wintering

Another common cause of the oleander's yellow leaves can be overwintering that is too warm, for example if you put the plant in a warm living room during the cold months. In winter, the evergreen oleander needs a break, so you should put it in a cool, but frost-free and bright place. The winter lack of light can also cause yellow leaves.


If other causes are not possible, check the size of the bucket. Choose the tub size as large as possible, as the roots of the oleander will need space. In addition, the plant should be repotted once a year.
