The tomato plant is a versatile fruiting crop that is easy to grow in many location types. Upside down hanging planters can be made for a low cost and offer benefits to the growing plants. Hanging tomatoes have increased air circulation for reduced disease problems and the fruit does not rot from touching the ground. Choose a tomato variety that has small- to medium-sized fruit to prevent the plant from being over weighted.
Start tomatoes plants from seed in early spring or purchase plants that are 3 to 5 inches in height with strong stems.
Scrub a 5-gallon plastic bucket with soap and water to thoroughly clean out residue. Verify the handle is attached tightly to hang the finished planter.
Cut a 2-inch hole in the center of the lid and bottom of the bucket with a hand-held saw. A drill with a saw blade for making doorknob holes will also cut through the plastic.
Cover the bucket hole with a coffee filter and fill the bucket with a lightweight potting mix. Gently shake the bucket to settle the soil as you add it.
Place a coffee filter on top of the soil so it lines up with the cover hole. Attach the cover tightly and flip the bucket over so it is resting on the cover.
Make a hole in the bucket coffee filter and plant a tomato in the bucket soil. Remove the lower leaves and plant the tomato as deeply as possible.
Place the bucket in a sunny location for 2 weeks with the tomato plant upright. This will establish the root structure.
Hang the bucket from a sturdy location once the plant is 1 foot in height. The tomato will now be hanging upside down.
Water and fertilize the tomato plant through the lid hole as needed.
