Geraniums overwinter - care in winter: overwinter

Now it is over again, the beautiful, warm summertime. And the many flowering plants, which were a real eye-catcher for the balcony and terrace, have already experienced the best days. But geraniums, for example, do not necessarily have to be disposed of when winter arrives. With few resources you can also overwinter these easy-care plants and will be able to enjoy them again next year.

Different possibilities of hibernation

Non-hardy pelargonium (Pelargonium) - to the family of the Cranesbill family (Geraniaceae) - can be brought in different ways over the winter. Since they do not need a hibernation, they can just continue to bloom in a warm room. Mostly, however, the plants are potted, cut back to finger length and then wintered in the dark and cool. But even outside, in milder regions, it is possible to bring them through the cooler season.

In warm conditions, a continuous flowering overwintering can take place

If there is enough space in the not too overheated living room or in a temperate conservatory, then the geraniums can probably be wintered there in the most comfortable way. For this, the plants only need to be controlled before being granted access to diseases and pest infestation. In addition, they can be cut before moving into the house. The pruning can also be done in the following year.

In the dark and cool, the bare plants are overwintered

The best location for wintering rooted bare plants is a dark and at the same time cool but frost-free room. This should be about a temperature between the +2 to +10 degrees Celsius prevail. Unfortunately, modern basements are often much warmer. Thus, for example, the garage, a garden shed or even an unheated conservatory or even an orangery can be the optimal location for the Pelargonium hibernation.

In more temperate climes they can be buried outside

In regions where the winter is mild, ie the temperatures drop to a maximum of 0 or -2 degrees Celsius, wintering in the garden itself may be possible. For this purpose a kind of ground rent is excavated. A loose layer of fir branches, twigs or straw is filled into this roughly 80 cm deep swathe. Then come the leafless, trimmed, and liberated plants. These are in turn covered with a layer of straw mats or the like and the hole is loosely filled with the excavation.

Instructions for wintering

It is important that the flowers are brought into the house before the first frost. It is best to use a warm and sunny autumn day, because then the roots can dry off. However, before deciding to overwinter the geraniums, one should also consider whether this is worthwhile for all plants. This means that first all withered leaves and all flowers, whether open or closed, withered or fresh, must be removed. This is necessary insofar as a blooming over the winter costs the plants a lot of power. By removing the flowers this power can be saved and the plant can concentrate better on hibernation.

Geranium geranium - Pelargonium

It is best to cut the plant back by a good third. This can also be examined well for possible pests or even sick roots. If such an infection is present, it is often no longer worth wintering.
In all other cases, however, the geraniums can be stored both in a planter and in various pots over the winter. These flowers are also the only ones that can overwinter even without water and can be hung upside down. However, it must always be ensured that even in the winter quarter, no pests are working on them. These would all too quickly spread to all other plants and destroy them as well.
The geraniums should be stored at temperatures around 10 to 15° C. It is best to have a bright conservatory or another cool but bright room. However, if such a room is not available, geraniums can also be wintered in the cellar. However, care should be taken to ensure that the root balls are only slightly moist, but not wet. Also, the regular and frequent check, whether a pest infestation has taken place, is indispensable. Especially in the dark cellar, they feel particularly comfortable.
From February on, the geraniums should be released from their dark dungeon. They need to be re-examined. Only if this investigation speaks for the re-planting, you can use them again. When the geraniums have been stored in the cellar, they often have developed very pale shoots.These should be removed before re-planting to make room for new shoots. Furthermore, the geraniums should not be put out immediately, because after a long storage in a dark, cool room they should not immediately get too much light and heat. It is best to put them in a bucket of water for a few days before finally planting them in pots or boxes. But these are then only once set up in the conservatory or another bright room. From the middle of April, they can be exposed for a few days, so that they are hardened. However, to finally put them back outside, the time is recommended after the Eisheiligen.
