Overwinter the lemon tree frost-free
Due to the lack of light in winter, lemons should always be kept in a cool, but frost-free winter. At temperatures below 12 ° C, the plants cease their root activities for the most part and require less light and nutrients, ergo they survive the unfavorable lighting conditions significantly better. A loss of leaves just towards the end of hibernation is not uncommon.

Lemons kept in the bucket overwinter best at temperatures of around five ° C, although the temperature of the thermometer during the day may well rise to 15 ° C. At night, about nine to twelve ° C are optimal. These temperatures correspond to the natural conditions of the lemon tree, although higher grades than 12 ° C are not recommended in the long run. In this case, the tree would wake up from hibernation.
Provide enough light
Since lemons are evergreen, however, they require a certain minimum amount of light even in cold wintering in order to maintain their vital functions. The usual light intensity in winter is not sufficient for photosynthesis and thus for the formation of assimilates - only a maximum of eight hours of daylight, filtered through the window glazing on top of that, acts like a permanent night on lemon trees. That's why in the living room, wintered lemons often shed their leaves in the spring or even react with dying, because they have no energy left over.
What to do with bright leaves?
Chlorosis, leaf whitening with leaf veins remaining green, are frequently observed deficiencies. The reason for this is the spillage of cold spring nights in spring and autumn, which makes it difficult to absorb nutrients through the roots. A large or even complete leaf loss, however, is almost always the result of too warm and / or too dark location in winter. However, the plant usually drives out again.
High humidity in winter quarters
As a third factor, the humidity has an influence on the plants. Increased humidity in the wintering quarter has both advantages and disadvantages.

Tips & Tricks
In winter, plant lamps should be installed as additional lighting. Also pay attention to the heat generated by the lamps - here, not least for cost-saving reasons, neon lamps are recommended.
