In winter, the plants must be protected against the cold, for example with fleece covers. The roots can be covered with a loose covering of leaves in order to prevent the root ball freezing completely. The leaves, too, need protection, as otherwise the plant may dry out due to the strong rays of the winter sun. A lot of water is evaporated from leaves subjected to the sun, and the water they then require cannot be supplied from the frozen ground. Camellias can cope with approx. -5 degrees without protection, and approx.
-15 degrees when covered with fleece.
The best location for them in winter is a slightly heated conservatory at temperatures of max. 15 degrees. However, it is important to leave the plant outside for as long as possible. If the camellia is stored in a too warm or dark location, it will be damaged. In order to develop its optimum flowering potential, the camellia requires cool temperatures. With the right ambient temperature, the flowers will stay for up to five weeks. Camellias are not suitable as houseplants.
They should not be watered much in winter, but should also not be too dry.
