Dry leaves after winter can be the result of frost damage

Why does oleander have dried leaves after the winter?

In its capacity as a plant from the Mediterranean, the Oleander conjures a Mediterranean touch in the local garden, but is not necessarily uncomplicated in the care. Especially during the winter, it is important to note some important information, so that the oleander does not get dried leaves after the winter.

Dry leaves due to frost damage

If the leaves are green and firmly attached to the shoots, but at the same time bone-dry and easily crumble, then they are likely to have frost damage. This can also occur when the plants were supposedly winterized - for example, were wrapped warm or wintered in a (not frost-proof) garden shed. With the frost-sensitive plant, a frosty night is often enough to freeze the oleander. Whether the affected specimen can still be saved, depends mainly on the nature of the roots: If they are intact, you can severely cut back the oleander and he will drive out new. But if the roots have gotten frost, the plant is in most cases beyond saving.


Oleander after clearing slowly get used to the sun

If the oleander gets dried leaves after the winter, this is not necessarily due to winter damage. Many damages are also caused by too quickly clearing out of the winter quarters. Basically, you should not place the oleander directly from the darker wintering in the sun. Instead, the shrub first belongs to the shade by the hour. The outdoor as well as the sun hours are extended only slowly.

Water oleanders regularly even in winter

Another common mistake in wintering the oleander is that casting is forgotten or rarely done. Although oleander needs much less water in the cold season than during the growing season, it should still be poured about once a week.

Dry rot often occurs after the winter

Dry leaves, inflorescences and shoots after the winter break are also often a feature of the so-called dry rot (Ascochyta), a typical oleander fungal disease. This usually occurs during or after hibernation and affects the aerial parts of the shrub, then gradually migrate towards the roots. This disease can only be countered with preventative spraying.


Tips

Generally cold wintered plants can generally be cleared out of their winter quarters earlier than warmer winters. The former have experienced a certain hardening over the cold season and are therefore more robust.
