Terracotta plant pot ensures good water drainage, preventing frost damage caused by waterlogging. The drainage hole should remain clear and can be covered with an upward-curved piece of clay if necessary, allowing water to flow out easily. Place the pot on feet to prevent it from freezing to the ground and to enable water to drain away from all sides. If possible, position the pot in a sheltered location away from rain and drafts to avoid saturation and the risk of destructive ice formation.
