Terra-cotta bowls are made from baked clay and the porous nature of this earth-based medium allows air and water to pass through the walls of the bowl.
The walls of the bowls draw the water out of the soil to help the soil dry quicker.
This promotes healthy plants by staving off root rot and disease caused by overwatering.
Terracotta containers are great for Cacti, Succulents, and other plants that prefer a drier soil.
