This may be because gardenia is watered too much, which makes it too wet, which makes it difficult for the roots to breathe and grow normally, and also makes the transportation function on it obstacle, which leads to the yellowing of leaves and the shedding of buds. In this case, it is necessary to put the flowerpot in a well-ventilated place to promote water evaporation and let the plants recover for a period of time.
Second, loam is too alkaline.
This is a plant that likes acidity. If the loam in the flowerpot is too alkaline, the leaves will naturally turn yellow, and the buds will not only drop, but also it is difficult to grow new buds. In order to ensure the acidic environment, ferrous sulfate can be applied once every half month, and it is best to keep the texture soft.
Third, improper sunshine.
Exposure to strong light will cause problems for plants, and the same will happen if plants stay in the dark for a long time without light stimulation. It can provide proper contact between sunlight and normal astigmatism.
Fourth, improper fertilization.
If too much fertilizer is applied, old leaves will wither and fall off, and flowers and bones will also fall off. If it is lack of nutrition, the newly grown leaves will turn yellow, so it is necessary to balance nutrition, apply Bika water-soluble fertilizer, and add it as appropriate according to the growth state.
