For small gardening areas, hanging planters are a clever way to maximize limited space. With an upside-down planter, you can almost double up on the plants in your hanging pots because a large plant grows out of the bottom of the container with smaller plants growing in the top. Upside-down planters lend themselves especially well to large plants that might require trellising, like tomatoes, peppers and cucumbers. You eliminate the need for stakes and trellises, and you can make the most of a sunny spot.
Find an appropriate place to hang your pot where it will get lots of sun. Remember that most vegetables and flowers need at least six hours of full sun per day. Since the plant will be hanging down, make sure it's in a place where it won't get bumped by people and doors.
Use a pot hanger, or securely attach a hook into a strong surface that will hold the weight of a large, full container.
Choose a plastic container that's large enough for the plant you want to put in it. Most vegetable plants need a pot that's at least a foot deep and a foot across.
Use a drill with a hole saw attachment to make a hole in the bottom of the container. The hole should be about 2 inches in diameter, or the same size as a hole for a doorknob.
Cut a slit in a piece of strong cloth. The slit should be large enough to put a seedling through it, but not so large that a lot of dirt can escape. Landscaping fabric, canvas or denim are all good types of cloth to use.
Select a seedling that is well-established, healthy and at least a foot tall. Vining varieties of plants will work better in an upside-down planter than bush varieties.
Lay the cloth over the hole in the pot. Hang the pot or have someone hold it up, then turn your seedling upside-down and carefully feed the foliage through the hole in the cloth.
Fill the pot with a rich potting mix that contains peat and compost, and water the pot. If desired, you can plant seeds or seedlings in the top of the pot as well.
