What to Do If Your Christmas Cactus Won't Bloom? Find the Cause and Fix It in Time
The Christmas cactus (Schlumbergera) is a cactus-type flowering plant. Its flowers are very red and vivid, appearing deep red, but this plant is rather difficult to grow, because the reason for its blooming troubles many flower lovers. Many flower lovers have grown Christmas cacti for several years without ever seeing their Christmas cactus bloom, so why is that? Below, Shuaishuai will tell everyone what to do when a Christmas cactus won't bloom!
Reasons why the Christmas cactus won't bloom and how to solve them
1. Light
Anyone who has grown a Christmas cactus knows that its light requirements are very low. It is not a full-sun plant. If it gets too much light every day, this will affect its blooming and make it hard for it to form flower buds, so it cannot bloom. This applies not only to sunlight outside; even indoor lamplight shining on the Christmas cactus will have the same effect as sunlight. Some growers like to place the Christmas cactus near a light at night, but this causes the Christmas cactus's differentiation to be affected due to too long a light exposure period, so the Christmas cactus cannot bloom. We should place it in an environment with light during the day and darkness at night, so that it can bloom.
2. Temperature
The optimal temperature for the Christmas cactus's growth is between 18-25 degrees, and the blooming temperature is between 10-15 degrees, and it must not exceed 25 degrees; keeping it at 15 degrees is best. In winter, the temperature for the Christmas cactus's growth must remain above 10 degrees for it to bloom normally; otherwise its flower buds will be frostbitten, and it is very easy to cause the flower buds to become blind buds. So when the temperature is too low, the Christmas cactus should be moved into a warm room, and moved out again after it blooms. After moving it out of the warm room, you must also observe the temperature at all times. Once the temperature is not up to standard, the temperature must be adjusted immediately to prevent the flowers from being frostbitten.
3. Watering
The soil in the Christmas cactus's growing environment should be semi-shaded and on the moist side. In the rainy summer season, the Christmas cactus should be put back indoors to ensure its flower buds are not damaged by rain. Water it less normally, because the Christmas cactus will not die from lack of water; it does have some cold tolerance, but waterlogging will cause its death, so watering must be done carefully and delicately. During the flower bud period, you must be sure to mist it with water at irregular intervals and keep the environment in a slightly moist state.
⟦NL>4. Fertilizing
When choosing fertilizer for it, you can choose phosphorus-potassium fertilizer and fertilizer containing a lot of nitrogen, such as horseshoe slices and ammonium sulfate, and you must control a certain amount. Many people may fail to control the amount when fertilizing, causing over-fertilization, which suppresses its development and prevents it from blooming, so nitrogen fertilizer should be applied a little less.
The above are the reasons why the Christmas cactus won't bloom and the solutions. After reading this, do you know how to solve it? In most cases, the Christmas cactus not blooming is closely related to light, because the Christmas cactus is different from other plants; it is not a full-sun plant, so we should reduce the light duration as much as possible while also ensuring that the amount of light it receives is sufficient.
