When it grows flower buds, don't touch the cold wind any more. If it is blown by the wind, it may cause the flower buds to fall. If the environment in the home is too dry, it can be properly ventilated and can't be in the sultry environment.
After the flower bud grows, its demand for water is obviously reduced, and the amount of watering needs to be controlled well. Do not water the same frequency as usual, and keep the pot soil dry. Too much water in the pot will cause the flower bud to fall. Root water control, but if the air is very dry, you can spray water to keep humidity, otherwise flowers and leaves will appear wrinkles.
The supplement of light can promote the synthesis of nutrients. After the flower bud grows, you can touch more sunlight, and you don't need sunshade, which can make the flower open better and more bright and beautiful.
Before the flower bud, you can add phosphorus and potassium fertilizer to ensure the flower bloom. After the flower opens, you should control the fertilization and stop applying fertilizer to it, otherwise the root will be hard to bear, resulting in rotten roots, and the whole plant will be damaged.
