Christmas cactus is a common flower in life. Because it is easy to grow and has the effect of purifying the air, many people like to grow some at home. So is Christmas cactus afraid of freezing in winter? How to maintain Christmas cactus in winter so that it grows vigorously? The following editor will explain them one by one, hoping to help you.

Is Christmas cactus afraid of freezing in winter?

Although Christmas cactus blooms in winter, it can only bloom under specific temperature conditions. Many flower lovers think that Christmas cactus blooms in winter and it feels cold-resistant. In fact, it is a tropical flower, so its cold resistance is not strong. When caring for it in winter, it must have suitable temperature conditions for it to bloom.

How to care for Christmas cactus and make it grow vigorously in winter

1. Temperature

Christmas cactus is not very cold-resistant, so it cannot overwinter in winter. It needs to be kept indoors so that it can grow normally. Otherwise, it may get frostbite in a low temperature environment.

2. Lighting

Christmas cactus has very strict requirements for light, because the light conditions directly affect whether Christmas cactus can bloom well. Christmas cactus is a very typical short-day plant, which requires 8 hours of light per day to bloom, so we can control the flowering period by adjusting the light time. For example, if you want Christmas cactus to bloom early, you can ensure that there are eight hours of light per day, and shade the rest of the time, which can promote the effect of flowering!

3. Watering

Christmas cactus is a succulent plant of the cactus family. Its stems and leaves contain a lot of water and nutrients, and it is very drought-resistant. It does not need a lot of water. In addition, the temperature in winter is low. If you still water it as before, frostbite may occur. Therefore, watering in winter should be less than in spring and autumn, and the water temperature should be kept consistent with room temperature.

4. Fertilization

Winter is the flowering period of Christmas cactus, so fertilization is also very important. Reasonable fertilization can make Christmas cactus bloom better. When fertilizing, phosphorus and potassium fertilizers should be used as the main fertilizers. The most common potassium dihydrogen phosphate can promote flower bud differentiation and bud formation, which is very suitable for use before flowering. In addition, microbial agents can be used some time before flowering, because microbial agents can not only meet the needs of plant growth, but also improve the soil, improve plant resistance, and reduce the occurrence of diseases and pests. Because the fertilizer effect is relatively slow, there will be no root burn!

Can Christmas cactus be exposed to the sun?

Christmas cactus has a shallow root system. Unlike cacti or the developed root system of leaf cacti, it is still necessary to avoid strong direct sunlight in the hot summer. Because Christmas cactus will enter a short dormant period when the temperature is stable and above 30 degrees in summer. It is best to shade it at this time and combine it with proper water control to safely spend the summer.
