Why won't the Christmas cactus bloom? All the solutions are here

The Christmas cactus is a plant that is both beautiful and able to protect against radiation. Many people like to keep it at home, and many people do not know that the Christmas cactus can bloom, because they have simply never seen a Christmas cactus bloom. So why won't the Christmas cactus bloom? Let's take a look together.

1. The time has not yet come

As for the Christmas cactus not blooming, one of the simplest reasons is that the time has not yet come, and "the time has not yet come" has two meanings: one is that the growth time has not reached the requirement for blooming, and the other is that it is not in the blooming period. The specific solutions are also different.

Solution: The blooming period of the Christmas cactus generally begins to form buds in October-November, does not begin to bloom until February of the following year, and does not begin to fade until early April. If it is not during this time, it is normal for the Christmas cactus not to bloom. The Christmas cactus is generally propagated by cuttings and grafting, and both require 2-3 years of growth time before it can bloom, so no matter how good the care is, if it has not grown enough, it will not bloom.

2. Improper lighting

The growth, development and blooming of any plant cannot be separated from sunlight, and the Christmas cactus is the same. It needs light for photosynthesis, and if there is insufficient light, it will be unable to bloom normally. However, the light that the Christmas cactus needs is not abundant light, but rather short light. For the Christmas cactus, short-day conditions are what allow it to produce better flowers, and if the light is too long, it may also fail to bloom.

Solution: In autumn, the Christmas cactus undergoes flower bud differentiation. At this time, ensuring short-day conditions is what helps it bloom. At this time, the Christmas cactus needs more than 12 hours of darkness each day. At night, it is best to place it somewhere without lamplight, so as to ensure normal blooming.

3. Temperature too high

Blooming in the Christmas cactus also requires a suitable temperature. The optimal growth temperature is 16-24 degrees. If the daytime temperature is too high or the nighttime temperature is too low, then it will also affect the blooming of the Christmas cactus. In addition, it should be noted that there needs to be a certain day-night temperature difference between day and night, so that its flower bud differentiation can be effectively promoted.

Solution: It is recommended to keep the daytime temperature at 20 degrees, and at night have a temperature difference of about 5-10 degrees compared with the daytime. Only in this way is it beneficial to its blooming.

4. Insufficient nutrients

Blooming in the Christmas cactus requires a certain supply of nutrients. Although the demand is not great, insufficient nutrients will affect blooming, resulting in small flowers or even faded flowers.

Solution: Before blooming and bud formation, you can apply cake fertilizer water once every 10 days, or apply a phosphorus-potassium fertilizer once, but note that nitrogen fertilizer must not be applied, so as to avoid excessive growth of branches and leaves without blooming.
