Here is a Patio Deck protector, 12 inch in diameter which can be cut to any size down to get 2 or 3 smaller pot risers. Made of durable polymer plastic, these guys allow for air to flow under the potted plant to keep your patio or deck dry and prevent rot to the surface. Could also be placed on a saucer but it would probably work better under a saucer in case it overflows with drainage. This way you will have the air flow to speed up the drying process.
