Drill 2 holes, 1 on each side of a plastic container. Thread wire through the 2 holes to create a handle to hang the container from. Bend the wire with a pair of pliers to keep it from coming out of the holes.
Place a shot glass at the bottom of the closed container. This will hold up the container on top so it doesn't sit in the water in the reservoir.
Poke a hole through the bottom of your other plastic container.
Cut a 1-inch-wide strip of cotton fabric. Thread it halfway through the hole at the bottom of the second plastic container.
Fill up the container with the fabric with potting soil. Coil the cotton fabric through the soil.
Plant your seedling. If transplanting it from another container, ensure it is planted at the same depth as in the previous planter.
Fill the reservoir container to the top of the shot glass with water.
Sit the container filled with soil into the container with the shot glass. Ensure the cotton fabric touches the water and begins to wick.
Hang the basket.
