Oleander is one of the potted plants that is very hardy and can be left outdoors well into the fall.

But you should fix yellow leaves quickly.

The oleander (Nerium oleander) is a shrub whose blaze of color is a colorful eye-catcher on the balcony or terrace.

Finally, the flowers of the plant, also called rose laurel, change color from pink, white, light yellow, salmon to many shades of red.

Therefore, they look great in the garden, especially in summer from June and with proper care, the plant will bloom into autumn.

Therefore, it is also one of the most popular potted plants.

But what to do if you discover yellow leaves on the bush?

Oleander has yellow leaves: This is often due to incorrect care

Owners often discover yellowing leaves on the lower part of the plant.

When these then fall off, the oleander bares from below.

However, the suspicious discoloration can also occur in the winter quarters.

Usually there are different reasons behind it.

The plant is not always ill immediately when the leaves turn yellow.

If the oleander has already been weakened by care mistakes, pests like to spread.

But it can be an indication that the care is not correct.

This can be due to the following errors:

  • Not watered properly or regularly

  • nutrient deficiency

  • Wrong location

  • Leaves are older (first turn yellow, then drop)

  • disease or pest infestation

Basically, the oleander, which sheds its leaves every two years, is a very robust potted plant, but it should not be neglected.

One of the most common reasons why the leaves turn yellow is that it is not getting enough water or watering it often.

Especially now in summer you should water the plant, which prefers to root on the banks of streams or rivers, several times on hot days.

Oleander also prefers calcareous soil, which is why it is best watered with tap water.

In addition, you should make sure that you add horn meal to the substrate every time you repot to prevent a nutrient deficiency.

In the summer, gardening experts recommend adding a liquid fertilizer that is specially made for flowering plants once a week.

Oleander has yellow leaves: when cancer is behind it

At the same time, it is not a problem for the plant to be outdoors in summer, after all, the evergreen shrub comes from the Mediterranean and likes to be in the blazing sun.

If the oleander gets too little light, the leaves compete for it.

With the result that the upper ones have an advantage and the lower ones discolour as a result.

However, if the leaves turn yellow and then brown, the plant may be infested with agarics.

You can tell by the fact that the diseased leaves have yellow spots and are not completely discolored and the leaf tissue eventually dies off.

If, on the other hand, there are black spots with a yellow border, it is oleander cancer.

This is caused by a bacterium.

It is best to act immediately and cut off the diseased shoots.

If the oleander is finally weakened for various reasons, pests such as mealybugs or scale insects also have an easier time of it.

But those who meet the needs of the plant in terms of care and location are usually spared.
