Answer 2

It is critical to periodically digging up the soil in the garden and pots as this enables the incorporation of oxygen in the soil and reinstates the fresh supply of oxygen and makes it airy.

With consistent watering, the soil may get clumped around the roots and become too heavy.  

Explanation:

• To make it loose and airy, it is critical that periodic digging up is done.
• Overwatering leads to waterlogging at the soil, and the plant roots are consistently subjected to a wet environment and this can lead to root rot.
• Therefore watering should be done intermittently and only after checking the plant type and whether the soil is dry of the plants.
