Gardenia buds turning yellow? It turns out these practices are wrong

Many people especially love growing gardenias, but gardenias sometimes develop yellow buds. There are two reasons for this.
If you notice that your gardenia buds at home, although they have already turned yellow, are still continuing to grow, it means the problem is with the soil.
When the pH of the soil is higher than the range it can tolerate, that is, when it is too high, the gardenia's leaves will first turn yellow-green, and the longer this goes on, the more obvious it becomes, and the buds will also turn yellow, but this will not affect its growth.
When you notice that the newly grown leaves of the gardenia start to turn yellow, use ferrous sulfate to adjust the soil and prevent the buds from turning yellow as well.
The other situation is that the buds not only turn yellow but also gradually wither. When this happens, there are many causes, and pests and diseases are the most common.
But among them, improper care can also cause it. For example, overwatering or overfertilizing. Pests and diseases can be prevented and controlled, but improper care is difficult to deal with.
Usually, pay attention to observing its leaves and the plant to prevent the occurrence of pests and diseases. If you water too much, its newly grown leaves will turn yellow, and if you fertilize too much, the tips of the old leaves will dry out and turn yellow.
