Overwintering of plants / potted plants overwinter: potted

In the case of potted plants that can overwinter in the garden (eg conifers, beech, bamboo, cherry laurel), it is important to protect the particularly frost-sensitive roots: Place the planter on boards or a polystyrene plate, the jute, reed, burlap or jar Wrap the nappy wrap and cover the shoots with dry leaves, brushwood or straw. The plants pushed together pushed to a house wall. In drought, they must be watered in winter, because the root ball must never completely dry out.

Ensure frost-free wintering

For most potted plants, however, a frost-free location is a must during the cold season. Before placing them, make sure that the plants are healthy so as not to infect any diseases into the shelter. Deciduous plants (angel trumpet (winter trumpet tree), bougainvillea, rose marshmallow, fuchsia, geranium, tuber begonia, blue mallow, etc.) are vigorously cut back. (Angel trumpets can be cut back to 40 cm stubs.) Flowers, buds, leaves and dry twigs are to be removed, as well as any weeds in the pot. Leafless plants are particularly easy to overwinter because they are content with a dark, frost-free space, such as Basement or garage. In addition, the absence of leaves reduces the risk of diseases and pests during the rest period to a minimum. And another pleasant side effect: you save space!

Choose bright locations

Evergreen potted plants (oleander, leadwort, citrus species, laurel, olive tree (olive tree winter), pomegranate) need a bright location even in winter. Conservatories would of course be the ideal case, but if necessary even unheated rooms such as the bedroom, the stairwell, the unused guest rooms or the cool hallway are sufficient. Insektizidstäbchen, put into the ground, here provide protection against pests. Sometimes it can happen that even these plants throw off their leaves. But even that is no cause for concern - but these flowers need next spring, of course, a little longer, until their original splendor is restored.

During the winter rest is generally watered very sparingly. The potting soil should always dry completely before it is poured. The plants gradually get used to the cold, reduce their metabolism and stop growing. They just want to be undisturbed during their break, so they will not be fertilized or repotted. Only now and then you should provide them with fresh air to prevent pest infestation - and remove discarded parts of plants to prevent fungal diseases.

Over-winter the potted plants indoors

Most sensitive potted plants are best for the winter months in a cold house, but some also require slightly higher temperatures. When choosing the room, it is essential to follow the care instructions for the plant.
A cold house is not available in every garden, but an alternative is the staircase or another room that is hardly heated, as well as a bright garage, a greenhouse or a shed. In addition to the right temperature, the light requirement of the plants also plays a major role. Deciduous plants can often overwinter in a dark room like the cellar, while evergreen trees need enough light for photosynthesis even in winter, so they can only be wintered in a bright room.

Olive tree - Olea europaea


The need for water in most plants is low in winter and fertilization should also be adjusted to allow the plants to maintain their natural rest periods.

Winterize potted plants outside

Frost hardy plants can overwinter outside in a tub. However, it should be remembered that their roots are much more exposed to the cold than the plants in the garden. Therefore, the bucket should be wrapped with a fleece, a bubble wrap or other insulating material even in plants that normally do not mind the cold.
To protect the roots from the cold from below, the bucket can then be placed on stones or wooden blocks. The most suitable location for most plants is a shady area near the house wall, where they are sheltered from the cold winter wind. It should be shady, so that the pot ball does not overheat in the sometimes very strong winter sun, because plants suffer in winter very underneath, that the root area is heated during the day and freezes again at night. A common problem with hibernation in the open air is dry damage because the plants do not get enough water.

Further wintering tips

In particular, plants that retain their foliage in winter must also be watered regularly during this time, because they also evaporate water over their leaves in winter.In the case of deciduous plants, it is easier to water more sparingly, but in both cases it is important to always plant the plants only on days when the temperature is above the freezing point. If there is only a sunny place for hibernation outside, some plants may need to protect the trunk from excessive sunlight.
Due to the large temperature differences on the sunlit and the opposite side, cracks can easily occur, so the trunks of these trees are best wrapped in jute. A shading net also ensures that the sunlight on the leaves is not too strong.

Basic tip

Most potted plants tolerate lower temperatures better than we assume. While minimal frost damage may be caused by light frost, it is much easier for the plant to cope with than too much hibernation under unfavorable conditions. The principle with regard to the winter quarters is therefore: late in the fall and early in the spring! This of course adapted to the sensitivity of the particular plant as well as the prevailing weather.
