Why should we not overwater potted plants?
It’s because the water will overflow and make the floor dirty.
Leaves of a plant take in oxygen from the air present in the atmosphere.
While, the roots, being buried in the soil, take in oxygen from the air present in tiny spaces of the soil.
When we overwater a potted plant, the air in the tiny spaces gets replaced by water.
So, do the roots know how to swim in water?
As air gets replaced by water, the roots do not get sufficient oxygen to breathe and they begin to rot.
This may adversely affect the growth of the plant.
Thus, we should always try to supply adequate water to the potted plants and not overwater them.
