Pot feet are essential for the health and well being of your plants. Even containers that have sufficient drainage holes can benefit from pot feet. The holes can get plugged up and then the water can't get out of the holes, which can drown your plants.
Some other advantages to elevating your garden pots is that more air can get to your plants' roots through the drainage holes, which is good for the health of the roots. Another big advantage to elevating your containers is that you protect your deck or patio from rot and stains by not having a soggy pot sitting direcly on it.
