Autumn is the right time to prepare the Mediterranean plant for the coming winter. This includes a caring pruning. Old plants are thinned out – you should not remove more than 30% of the old shoots. The remaining branches are shortened to the first bud. In addition, the oleander is also checked for pests and diseases, ailing and dead parts of the plant are removed immediately.

If the oleander has not bloomed as vigorously as before for a few years, then you can rejuvenate it in January. But you must expect that the plant will recover in the framework of next year and will not form flowers.

Cut off oleander seed pods

If you want to extend the flowering period of the oleander, then you should cut off the green seed pods. Do not allow the seeds to mature, but cut them off immediately after they form. This way you can encourage new flower formation. Removing the seeds is also recommended because otherwise the woody plant will put its energy into the seed capsules and will then be more sensitive to frost.

Wintering oleander: The most important questions answered

Oleander pruning in autumn thinning tips

The oleander is a true sun worshipper. It thrives best in full sun locations, needs wind and rain protection in the summer. As long as the weather permits, you should leave it outside even in September. The exotic is wintered before the first night frost. It can poorly tolerate sub-zero temperatures.

Oleander care: can you overwinter the exotic outside?

The exotic is common in the Mediterranean region and can not tolerate rain, snow and low temperatures. Therefore, wintering outdoors is out of the question. Prepare winter quarters and bring it into the apartment or house in mid-October. In September, the plant is placed close to the house, watered only when necessary. The tub is wrapped with fleece and thus protected from frost .

Wintering oleander in the dark basement or garage: is it possible?

Oleander care as a tub plant in autumn and winter


The oleander is a tub plant, but it can quickly grow in height. Perennial plants take up a lot of space and are heavy to boot. One wonders then if the oleander can perhaps be overwintered in the cellar or garage. The problem is that the exotic plant needs a sunny place even in winter. The garage and the cellar offer enough space, but they are too dark and poorly ventilated.

However, a short stay in the garage or basement can not harm the plant. In regions with mild climates, the woody plant can remain outside all year round. It is best to place it near the wall of the house, preferably protected from the wind and rain. Place the tub on a styrofoam coaster and wrap it with frost protection film. If the temperature drops below – 5 degrees Celsius for only a short time, then you can bring it into the garage.

Wintering oleander in the apartment

Optimal conditions for the sun worshipper is a winter garden or a greenhouse. Place the container on polystyrene coasters and wrap it with fleece, if you overwinter the oleander in the greenhouse. Scatter a layer of mulch on the surface.

An unheated room in the apartment or house also works well as winter quarters. However, make sure that the oleander is not too warm. Temperatures should be between 8 and 12 degrees Celsius. If the oleander is placed in a dark room, then it should be wintered at 8 degrees Celsius. Conversely – if it stands sunny, then it can be overwintered at temperatures up to 12 degrees Celsius.

You can stop giving fertilizer at the beginning of September. Oleander does not need fertilizer to get through the winter. Even vice versa – fertilizers can stimulate growth and young shoots are particularly sensitive to frost. They are also more often attacked by pests in the fall.

As for watering, the rule of thumb is to water the plant sparingly, but regularly. The soil should never dry out; the exotic prefers moderately moist soil.

Oleander overwintering: The right room temperature

The overwintering of the oleander is especially important for wintering out. Basically, plants that spend the winter in a cold room can be placed outside as early as March or April. In this case, the acclimation period is very important. The exotic needs time to feel comfortable in the garden again.

Plants that have been overwintered warmly may only be put outdoors after the Ice Saints. Even then, the exotic needs some time to adapt to the outdoor light conditions.

Oleander care in autumn and winter includes measures related to wintering and pruning. Starting in mid-September, you should slowly prepare the exotic for the coming winter and choose the appropriate winter quarters. Before the first frost, around mid-October, it is wintered warm and bright.
