Outdoor fountains add a whimsical element to your patio and landscape. Using decorative flower pots as the water basin is one of the simplest ways to make an outdoor fountain, but make sure to bring the fountain inside during colder temperatures. Terra cotta and ceramic flower pots can crack if the water freezes or if temperatures drop quickly. Embellish a terra cotta pot with acrylic paints or cover it with mosaic tiles to enhance the design. Ceramic flower pots are often already decorative and require no further enhancement.
Spray paint the four wooden feet to blend in with the colours in the largest flower pot. Let the paint dry. Attach the feet to the underside of the largest flower pot using waterproof construction adhesive. Allow the glue to dry. The feet raise the flower pot so that you can thread the power cord from the fountain pump to the electrical socket or solar panel.
Place the submersible fountain pump inside the largest flower pot. Fit the power cord through the drainage opening in the planter. Cut a rubber disk to fit over the drainage hole; slit the disk halfway across to fit around the cord. Fit the rubber disc around the cord and over the hole. Use silicone sealant over the slit and around the disk.
Cut a 90 cm (3 foot) strip of plastic tubing. Attach the tubing to the fountain spout. Stand the two bricks on their ends inside the 40 cm (16 inch) flower pot. Place the bricks on opposite sides of the rubber disk; glue them in place with waterproof construction adhesive. Extend the plastic tubing up between the bricks.
Thread the plastic tubing through the drainage opening on the 30 cm (12 inch) flower pot. Glue the base of the 30 cm (12 inch) pot to the top of the bricks with waterproof construction adhesive. Cut another rubber disk to fit over the drainage hole and the plastic tubing in the 30 cm (12 inch) flower pot. Fit the rubber disk in place and seal it with silicone.
Stand two half-bricks, end up, on each side of the rubber disc in the 30 cm (12 inch) diameter pot. Glue the pots in place. Extend the plastic tubing between the bricks and feed it through the drainage opening of the 20 cm (8 inch) flower pot.
Glue the 20 cm (8 inch) flower pot to the upright bricks in the 30 cm (12 inch) pot. Cut and seal a rubber disc over the drainage hole and around the plastic tubing. Fill the 20 cm (8 inch) pot with decorative glass stones to within 5 cm (2 inches) of the rim; keep the plastic tubing extended in the centre of the flower pot. Cut the plastic tubing so that it ends 2.5 cm (1 inch) below the rim of the 20 cm (8 inch) flower pot.
Camouflage the fountain pump and the bricks in both of the two larger flower pots with decorative stones. Fill all three flower pots with water before starting the fountain pump. The water will flow over the 20 cm (8 inch) pot and into the 30 cm (12 inch) pot; over the 30 cm (12 inch) pot and into the 40 cm (16 inch) pot. The pump will recirculate the water from the 40 cm (16 inch) pot, back up to the 20 cm (8 inch) pot.
