Hanging tomato plants to grow is a smart way to conserve space and works extremely well for small areas such as apartment balconies when you want fresh summer tomatoes but do not have the room for a garden. Look for determinate tomato varieties for hanging since they grow to a manageable size, not too large for hanging pots. Hanging tomatoes to grow is extremely simple and inexpensive, and the reward will be fresh, vine-ripe tomatoes during the summer.
Use a 5-gallon bucket for hanging your tomato plant. Drill or cut with a utility knife a 3-inch hole where the indentation is in the bottom of the bucket. Set the bucket on two saw horses so the hole is between them.
Remove the first two set of leaves from the bottom of the tomato plant. Holding the plant upside down inside the bucket, thread the top of the stem down through the hole in the bottom of the bucket so only about 1 inch of the stem is poking through.
Add peat moss to the inside of the bucket while holding the tomato plant in place. Cover the roots entirely with the peat moss. Press down gently around the hole on the inside of the bucket to help hold the tomato plant in place. Once firmly in place, let go of the plant.
Fill up rest of the way with potting soil to within 1 inch of the top of the bucket. Hang the bucket by the handle in a sunny location. Water thoroughly until the water runs out of the bottom of the bucket. If the soil has settled more than an inch, add more.
Water the tomato plant deeply about once a week or more. Keep the soil moist, but never soggy. Water if the top 2 inches of the soil is dry to the touch.
Feed your tomato plant within one week after planting with a water-soluble balanced fertilizer, 10-10-10. After that, fertilizer every two weeks until the plant begins producing fruit, at which time you can stop fertilizing.
