Why does too much watering lead to the death of flowers and plants?

When the potted flowers are watered too much, the water fills the soil gap, and the air in the soil is replaced by water, so the external air can not enter, which results in soil anoxia, hindrance of root respiration, decrease of physiological function and hindrance of root water and fertilizer absorption.

At the same time, due to the lack of oxygen in the soil, a large number of aerobic bacteria with the function of decomposing organic matter in the soil multiply and move, which increases the acidity of the soil. Due to the extensive activities of butyric acid bacteria, a series of toxic substances such as hydrogen sulfide and ammonia were produced, which directly poisoned the root system. At the same time, because the anoxic plants consumed a large amount of soluble sugar and accumulated too much alcohol and other substances, the photosynthesis was greatly reduced, and finally the flowers died of hunger.

In the practice of growing flowers, we can often see that the roots of flowers turn black and rot and drown because of too much watering. Therefore, we should pay attention to the right amount of watering when cultivating flowers.
