This problem involves what we call the growth environment of flowerpots, soil, and roots. The growth of flower roots requires moisture and fresh air.


The space of the flowerpot is small. If the air and water permeability of the soil and the flowerpot are poor, water will accumulate when watering too much. Once water accumulates, there will be a lack of air in the pot soil. Short-term lack of oxygen, the roots cannot absorb nutrients, and the plants will gradually wither; long-term accumulation of water, the carbon dioxide and other waste generated by the respiration of the roots cannot be discharged out of the roots in time, which will cause fermentation, rotten roots, and the flowers will die.

Watering flowers is the most common daily work and the main cause of flower death. Because the amount of watering and the watering time are specifically handled according to many factors. For example, the summer is hot and water evaporates quickly. For plants that are in the vigorous growth period, water more, otherwise they will wilt and die. But for plants that dormant in summer, do not water more, otherwise they will accumulate water, rot their roots and die. For another example, different plants require different amounts of water, different flower pots, different cultivation substrates, and changes in the weather have different speeds of water evaporation. These will affect the amount of watering.Therefore, to plant a flower, we must first figure out when and how much to water.
