When it enters the gestational stage, it can't be filled with too much water. As a result, too much water will accumulate in the flower soil, which will not only affect the root to absorb water and nutrients from the flower soil, but also may make its roots rot, causing damage to it, thus making the flower buds black and fall off; secondly, once too much water is replenished, it is likely to turn into a long-term growth, branches and leaves will grow in large quantities, consume too much nutrients, causing the flower buds black and fall off.
Solution: if you don't make up too much, stop making up water first, and then use chopsticks to insert several holes in the flower soil to help the water quickly spread out. If you make up too much, you need to take it out of the flower soil, shake off the surrounding flower soil, cut off the rotten roots, and then plant it into the new flower soil.
Many flower friends think that it needs a lot of nutrients to bloom, so when its bud appears, they will give it a lot of fertilizer. In fact, this method is very wrong, because flowering mainly consumes nutrients in the plant, so we don't need extra fertilizer, on the contrary, adding fertilizer to it at this time will easily burn its root, causing the flower bud to fall off.
Solution: if the situation is relatively light, we can add a lot of water to the basin, wash off the residual flower fertilizer in the flower soil, and then pad some stones at the bottom of the basin to volatilize the water; if the situation is serious, we also need to replace it with new flower soil.
Some flower friends know to give it a flowerpot, but maybe because the technique of changing a flowerpot is not very skilled or the times of changing a flowerpot are too many, so that its root is damaged in the process of changing a flowerpot, which will also affect the absorption of water and nutrients of the plant, so that the flower buds become black and fall off.
Solution: This is relatively easy to solve. First of all, we need to cut off some branches and leaves to reduce the water consumption. Then we need to put it in a cool place for about 10 days. During this period, we don't let it bask in the sun, but we can't completely lose the light. We'd better scatter the light to it. When the new leaves grow out, you can take care of them normally.
