If you have limited ground space, or don't have time to deal with the many insects or soil problems associated with growing tomatoes in the ground, you have another option. You can plant a tomato plant upside down. Using hanging tomato plants you can add both a touch of decoration and grow your own food both indoors and outdoors. If you have grow lights and a timer you can plant tomato plants upside down and grow them in closets or in basements as well.
Turn the bucket on end with the bottom face up. Find the center of the bottom by using the measuring tape. Make four points 1 inch off the center around the bottom of the bucket. Cut a hole in the bottom with the knife using the points as a cutting guide. Eliminate sharp edges around the cutout by shaving them down with the file.
Set the lid flat on the work surface. Find the center of the lid by using the measuring tape. Make four points 1 inch off the center around the lid of the bucket. Cut a hole in the lid with the knife using the points as a cutting guide. Eliminate sharp edges around the cutout by shaving them down with the file.
Turn the bucket right side up. Tape a coffee filter flat over the holes in both the bottom of the bucket and the underside of the lid. Pour the entire bag of potting soil into the bucket. Put the lid onto the bucket and secure it.
Turn the bucket on end again. Cut through the coffee filter at the bottom of the bucket with the knife. Dig into the soil until your fingers are all the way in. Pull out the dirt and set it aside, creating a hole. Insert the tomato plant by the roots into the hole until the base of the plant is in the dirt. Put the removed dirt back into the hole, covering the roots. Water the soil until it is damp. Leave the bucket alone for seven days. This allows the roots to set themselves into the soil.
Pick up the bucket and turn it over right side up. Hold the bucket by the handle for the remainder of this step. Cut out an "x" in the filter at the center of the hole. Fold the filter underneath the edges. This is where you will give your tomato plant water.
Hang the planter on a sturdy horizontal pole or hook. Keep the bucket and plant in a sunny location where the plant will get 12 hours of sun or light.
