Bringing camellias well over the winter is not rocket science. Nevertheless, there are a few important points to consider so that they can survive the cold season well.Camellias can tolerate low temperatures well
The plants have to hibernate properly so that camellias can bloom again in the next year. But don't worry, there are only a few points to consider.
Generally, camellias can tolerate low temperatures well. As an evergreen balcony plant, they even need low temperatures so that the flower buds can open in spring.
Suitable places for wintering
Wintering in the greenhouse:
After the fall, camellias need around 8 weeks as a rest phase to prepare for the winter. It is important that you place the plants in a cold and bright place. Frost-free greenhouses are best suited. The winter camp should have a constant temperature between 0 and 10 degrees. The humidity should also be a constant 60 percent.
Wintering in the basement:
If you prefer to spend the winter in the basement of your camellias, then always make sure that the temperature does not rise above 15 degrees Celsius. High humidity is also important. Therefore, spray the plants in the basement regularly with lime-free water. A humidifier is also helpful. If the air humidity falls below 60 percent for a long time, the plants can throw off their flower buds. This is a known reaction of the camellia when the temperature is too warm.
Wintering in the apartment:
All those who have not found a suitable winter camp can leave their camellias outdoors for as long as possible. However, the temperature must not drop below 5 degrees Celsius. Then bring the plants into the house as short as possible and release them again after the end of the frost period.
Preparations for the return from the winter camp
During the months of January and February, the camellia is normally in hibernation. Subsequently, night temperatures of 6 to 12 degrees Celsius are sufficient for the plants. However, they need a lot of light. A greenhouse is therefore ideally suited to prepare the camellias for the upcoming flowering period. Here they can stay until they drop out.
The camellias overwintered in the basement, on the other hand, are only allowed to get used to higher temperatures slowly. It is helpful if you water the plants more often without creating waterlogging.
Wintering of outdoor camellias
There are no hardy camellias. However, temperate climates can also be found in our latitudes. Camellias can spend the winter outdoors, especially on the Rhine Rift, in the coastal region or on the Lower Rhine. Even in protected gardens, these plants survive the cold season. However, you need a few precautions:
There must be adequate protection from the winter sun, otherwise the plants will dry up. You can e.g. shade with fleece. You can also protect your outdoor camellias from the winter cold with fir branches, reed mats, a thick layer of mulch or other materials.
Furthermore, there must be permanent wind protection, which is represented by hedges and fences, for example.
On frost-free days, the plants should be watered a little to prevent them from drying out.
