1. -- Regular Pruning --
During the period of vigorous growth of Christmas Cactus, pruning should be carried out to cut off some overgrown, dense, diseased and withered branches. This can not only avoid excessive consumption of nutrients, but also promote healthy growth of branches and leaves. After flowering, the remaining flowers can be pruned and some branches and leaves can be pruned. After pruning, not only is it beautiful, but it also helps to bloom quickly.
2. -- Reasonable Fertilization --
Christmas Cactus needs a lot of fertilizer during the growing period and flowering period. It can be applied with 1000 times monopotassium dihydrogen phosphate solution every half month during the growing period. Phosphorus and potassium fertilizer can be topdressed during the bud period to promote differentiation of flower buds and rapid flowering. After flowering, fertilization should be gradually reduced, and a small amount of base fertilizer can be applied before entering winter.
3. -- Sufficient Lighting --
Christmas Cactus does not have high requirements for lighting, but necessary lighting conditions must be available every day. In spring and autumn, 7-8 hours of lighting can be maintained every day. In summer, proper shading should be provided, and avoid direct sunlight. In winter, it can be placed in a sunny place indoors.

Can Christmas Cactus Be Covered with an Oil Drum for Insulation in Winter?
It is not recommended to cover Christmas Cactus with an oil drum for insulation in winter. Christmas Cactus is prone to powdery mildew in a warm and humid environment, and a ventilated and scattered sunlight environment is more conducive to moisture evaporation. When covered with a transparent container, the moisture evaporated by its own respiratory function will remain on the leaves for a long time, coupled with the lack of sunlight and ventilation, a long time of warm and humid environment will reduce the resistance of Christmas Cactus, making it more susceptible to disease.
Covering potted plants with a transparent container in winter is mainly to create a small greenhouse environment:
Covering plants with a transparent container for insulation is mostly used for succulent plants.
Especially for succulent plants with high transparency of fleshy leaves, such as jade dew, jade fan, longevity, and universal, under the premise of improving environmental temperature and preventing frostbite, the transparency and plumpness of fleshy leaves can be made more plump and transparent.
But succulent plants have small plant type and small volume, which is easy to operate. Other cold-resistant potted plants generally adopt the way of making a small greenhouse for convenient management.
In addition, if the number of potted plants at home is not particularly large, it is only necessary to place potted plants in a closed balcony and indoors for a short time in winter to naturally spend the winter, without too much trouble.
In the south without heating, an additional supplementary light can be added, temporarily gather all the flowers and plants together for maintenance, increase the lighting and slightly increase the ambient temperature at the same time, killing two birds with one stone.
It is Not Recommended to Cover Christmas Cactus with an Oil Drum for Insulation in Winter
Christmas Cactus is prone to powdery mildew in a warm and humid environment, and a ventilated and scattered sunlight environment is more conducive to moisture evaporation.
When covered with a transparent container, the moisture evaporated by its own respiratory function will remain on the leaves for a long time, coupled with the lack of sunlight and ventilation in the indoor environment in winter, a long time of warm and humid environment will reduce the resistance of Christmas Cactus, making it more susceptible to disease.
It is better to keep it in a relatively stable natural environment. As long as the environmental temperature is not lower than 5°C, the pot soil will not be frozen.
Although the roots of Christmas Cactus are not developed, as a member of the cactus family of succulent plants, it is not as delicate as you think!
Problems with Christmas Cactus in winter are often caused by excessive watering, long-term waterlogging in the pot, lack of sunlight, and large temperature differences between day and night, which lead to falling flower buds. Frostbite is not a fatal injury!
