This old idea is a great one.  Raise up your plant pots with these simple clay feet, 3 will do the trick for any round planter.  Space them evenly around the base of your pot and this will allow proper drainage for your planter.  No more water stains on your decks or walkways and no more creepy crawlies nesting under your plantings. 

But, the best reason to use these is to provide proper drainage for your pots.  This is recommended for all our planters to keep them safe through the freeze thaw cycle of our North American winters.  Sold in sets of three.
