Making your own flower pots is simple and inexpensive with homemade clay. Clay recipes are widely available online; most ingredients include common household materials that you likely already have on hand. The molds for the flower pots may also be common household items or containers that may be headed for the garbage can. Get the kids involved to make and decorate flower pots for a creative garden.
Mix a 2-to-1 ratio of baking soda and cornstarch in a saucepan.
Measure 1 1/4 cups of cold water for every cup of cornstarch you used in the mixture. Add food coloring to the water and mix it with a spoon. Make the water as dark or as light as you like.
Pour the water into the saucepan with the baking soda and cornstarch. Stir the mixture over medium heat until the consistency is that of mashed potatoes. This may take four to five minutes.
Empty the contents of the saucepan onto a plate. Cover the clay with a damp towel until it cools.
Cut out the bottom half of a plastic milk jug. Clean and dry the inside of the milk jug thoroughly. Coat the inside of the milk jug with cooking spray. The cooking spray will act as a release agent for the clay mixture.
Shape the cooled clay inside the milk jug to form your flower pot. Make the bottom and edges of the flower pot about 1 inch thick.
Remove the shaped flower pot from the milk jug and place it on a foil-covered baking sheet.
Press colorful flat-backed glass cabochons around the outside of the flower pot. Decorate the flower pot with as many glass bits as you like. Mosaic tiles or broken bits of ceramic are also nice decorations for your flower pots.
Puncture the bottom of the clay flower pots with a knitting needle to make drainage holes. Allow the flower pot to dry overnight before planting.
