Pot Pads are a clever new solution for patio gardeners. They suction to the bottoms of pots and planters, creating an air space between the pot and the deck surface. This prevents rotting and water build-up, and eliminates damp spaces where slugs and woodlice like to gather. The dome shape of the bottom of each pad creates a minimal point of contact with the patio surface, and makes it easy to move pots once they are installed. Each pack comes with four pads, the recommended number for one pot. The added space beneath each pot means better drainage and root aeration, and healthier plants.
