People who have limited space or who already have a full garden can easily grow hanging tomato plants. Commercial hanging tomato systems can be expensive, but you can make your own out of materials you may have lying around the house. Hanging tomatoes need the same kind of light as ground-grown tomatoes. Choose a sunny location to grow your hanging tomatoes. Harvest your tomatoes as they ripen to reduce the weight of your hanging tomato plants.
Drill a 2-inch hole in the bottom of a 5-gallon bucket. This is where you will plant your tomato plant. Use a hole saw attachment on a drill to make the hole.
Drill another 2-inch hole in the lid. You will water your tomato plant through this hole.
Fill the bucket with potting soil.
Cover the hole in the lid with a coffee filter to keep the soil from dropping out as you plant the tomato plant.
Place the lid on the bucket and turn it upside down so it sits on its lid.
Plant a young nursery tomato plant in the bottom. Water the plant until water drains out the bottom and allow it to grow for a week. This will allow the roots to grow long enough to hold the plant in the bucket.
Turn the bucket over and hang it upside down. Water through the hole in the top or remove the lid entirely.
