There are generally two reasons for the blackening of leaves in gardenias commonly kept in households. One is improper fertilization, such as excessive fertilization. The other is the necrosis of its root system, which means root rot.
Improper fertilization and excessive fertilization can cause the leaves to turn black, for instance, when we use an overly concentrated fertilizer at one time, causing root burn. After the roots absorb too many nutrients, the leaves show blackening and drying at the edges, very quickly, especially when using nitrogen fertilizer. The leaves are most prone to burning in this case. Also, using too much ferrous sulfate can cause this condition. Do not use too much ferrous sulfate, dilute it at a ratio of 1:1000, and apply it once a month. Try to water the roots instead of spraying the leaves. Spraying the leaves is difficult to control the concentration and amount, which can easily lead to leaf burning.
The other situation is root rot. If the soil used for planting gardenias is not loose and well-ventilated, and it does not dry for a long time after watering, it can cause root rot. The initial manifestation of root rot is the gradual rotting and drying of the leaves. This is a signal to promptly address the issue by changing the potting soil to a loose and well-ventilated one, cutting off the rotten roots, planting it, and消毒 the soil. Soak the roots in代森锰锌 to allow it to grow well. When growing gardenias, it is important to maintain good ventilation. Poor ventilation will cause the potting soil to dry slowly and is prone to root rot. This is the same for growing any plant; ventilation must be good.
There are only these two reasons for the gardenia's烂叶 condition. Analyze your situation to solve it effectively.
