CATDOLL : CATDOLL: Detailed explanation of 3 reasons why Christmas cactus does not bloom and how to deal with it

With the improvement of living standards, many flower lovers will grow some Christmas cactus at home. If the Christmas cactus does not bloom, it would be a big spoiler of the scenery. Many people do not know the reason why the Christmas cactus does not bloom. Generally speaking, it is mainly caused by long lighting time, inappropriate temperature and improper fertilization. At the same time, we should also pay attention to the treatment of Christmas cactus after flowering, as well as the treatment of diseases and pests. Only in this way can we cultivate a more beautiful and lush Christmas cactus.

1. Reasons and treatments for Christmas cactus not blooming 1. Too long light exposure time

Because Christmas cactus is a short-day plant, if the sunshine time is more than 10 to 12 hours a day, the roots will not get nutrition and growth. It is difficult to form flower buds, and flower buds naturally cannot form, resulting in the loss and consumption of nutrients. In addition, it cannot be illuminated by electric lights for a long time at night, which will also affect the flowering of flower buds.

Solution: It is best to maintain 8 to 10 hours of light per day, and place it in a dark and cool place at night. It should not be placed outdoors for too long in the summer. It is best to keep it in a semi-shaded and semi-sunny state, and shade it from time to time, and maintain good ventilation. This will help the formation of flower buds and is beneficial for flowering.

2. The temperature is not suitable

The suitable temperature for Christmas cactus during its growth period is generally 20℃~25℃, and the flowering temperature is 15℃~25℃. It is best not to exceed 25 degrees. Because Christmas cactus is not cold-resistant, it is best to keep the daily temperature at around 20 degrees. If the temperature is too low, it will affect the formation of flower buds of Christmas cactus, and the buds will develop slowly, resulting in slow flowering or even no flowering.

Solution: It is best to heat it in winter, and place it indoors or in a greenhouse, and keep it in normal light every day. In summer, if the temperature is too high, move it indoors and place it in a ventilated place.

3. Improper fertilization

Many people don't know the reason why Christmas cactus doesn't bloom. In fact, fertilizer is the main reason. Christmas cactus likes loose organic fertilizers, and the root system tissue is relatively weak and easily damaged. If too much nitrogen fertilizer is applied, and there is an insufficient supply of phosphorus fertilizer and potassium fertilizer, the root development will be inhibited due to the strong nutrition. This will destroy the root tissue system and naturally prevent it from blooming.

Solution: It is best to use organic fertilizer as the main fertilizer for growing Christmas cactus, and nitrogen, phosphorus and potassium fertilizer as the secondary fertilizer, because the organic matrix is ​​conducive to the growth and development of the roots, and less nitrogen fertilizer is applied. This will maintain a balanced nutrition and allow normal growth and flowering.

2. Treatment methods after Christmas cactus flower 1. Pruning

After flowering, Christmas cactus will enter a dormant period. Most of the nutrients have been consumed during the growth period. When it blooms, the root development is slow and the buds are formed slowly, so it enters a dormant period. Therefore, pruning after flowering is also a very important stage. When Christmas cactus blooms, you can cut off the excess side branches to avoid nutrient consumption. This can concentrate nutrients and is conducive to the next flowering growth.

2. Suitable temperature

Generally, after the Christmas cactus blooms, it is necessary to prepare for the next flowering. After the Christmas cactus blooms, it will enter the next stage of flowering and growth. At this time, the stems and buds will grow again, so it is necessary to ensure the appropriate temperature, the right amount of water and fertilizer, and the reasonable light time every day, which will speed up the effect of the next flowering.

3. Disinfection of potting soil

The soil in the pot of Christmas cactus needs to be reprocessed after flowering. Because the root system of Christmas cactus will consume a large amount of nutrients in the soil when it is potted, the nutrients in the soil will decrease after flowering. Since the demand for nutrients is relatively large during the growth period, the soil in the pot should be disinfected first after flowering, and then repotted to ensure the normal growth and development of the plant.

3. Diseases and pests of Christmas cactus flowers and their treatment methods 1. Red spider mites

The most common pest of Christmas cactus after flowering is red spider mites, which are extremely harmful. They mainly attach to the leaves and absorb nutrients from them. They have strong reproductive ability and will quickly accelerate the aging of the leaves and even cause the death of the plant. It is best to spray omethoate solution irregularly and sterilize once every two weeks.

2. Scale insects

Scale insects appear more frequently after Christmas cactus flowers bloom, mainly in the form of white spots, slowly forming a large area of ​​brown bacteria, mainly on the leaves and the epidermis of the plant. The damage is relatively large and will directly lead to the withering and falling of the plant. It is best to remove it with bamboo strips in the early stage of extinction, and then rinse with clean water. In severe cases, it can be sprayed with phosmet emulsifiable concentrate solution.

Conclusion: Through the above introduction, I believe everyone has a deep understanding of the flowering of Christmas cactus. It will be convenient to avoid the occurrence of Christmas cactus in the future planting process, and it is also possible to cultivate Christmas cactus with lush branches and green leaves.
