Cut out a section of a piece of firewood or a fallen tree branch with the hand saw. The tree branch should be 12 inches in diameter. Cut a section that is 2 feet tall.
Paint the branch section with a thin layer of exterior wood sealer according to the package directions on the sealer. Paint the top and bottom of a wood craft plaque 24 inches in diameter. Let both pieces dry for 24 hours.
Cover the top of the branch cross section with wood glue and place the plaque on top. Stack heavy books on the plaque to keep pressure on it, and leave it for 24 hours so the glue can cure.
Remove the books. Set the plant stand in a sunny pot and put your potted plants on top.
