Terracotta plant pot ensures good water drainage, preventing ice formation caused by waterlogging from cracking the container. The drainage hole should be unobstructed and can be covered with an upward-curved piece of clay to allow for proper water flow. Place the pot on feet to prevent it from freezing to the ground and to enable water to drain freely in all directions. If possible, position the pot in a sheltered location away from precipitation and drafts to avoid saturation and the risk of damaging ice formation.
