Choose the Right Pot
Tomatoes will grow in traditional hanging baskets and upside-down tomato pots. Although novel, upside-down hanging pots present many practical challenges for growing tomatoes. Plants naturally want to grow up toward the sun. When planted upside down in a special container, the tomato stems bend and form a U shape as they attempt to grow toward the light. The bent stems are weak and easily snap under the weight of fruit or during high wind. Upside-down pots also have the potential to partially shade the developing plant. Be sure to select a location that has ample direct sunlight for best fruit production. The best upside-down hanging tomato pots are made out of sturdy buckets; the popular thin, breathable plastic planters dry out far too quickly for practical use. During hot and dry conditions, breathable plastic planters require watering more than once a day. Choose a planting bucket that is light in color; dark-colored pots can cause the plant’s roots to get too hot during the heat of summer. Size is important when choosing a traditional hanging basket or upside-down pot for a tomato. Select a pot that is 12 to 24 inches in diameter and holds at least 5 gallons of soil. Tomatoes have extensive root systems. Not only do their root systems fuel the plant’s top growth, but they also anchor the plant in the pot. Plenty of soil is essential for a strong plant.
Focus on Light
All tomatoes require 8 hours of direct sunlight to grow and fruit well. When choosing a location for your hanging basket tomato plants, look for a spot that isn’t shaded by a nearby building, roof, or trees. Be especially mindful of porch roofs, which tend to be common places for a hanging plant—porch roof hanging locations tend to cast too much shade for tomato plants. The best tomato hanging basket location is likely on the south side of a building. In Zones 7 and above, a hanging spot that receives a few hours of shade from the intense afternoon sun is preferred, while Zones 6 and below can tolerate a full day of sun.
Invest in Ultra-Strong Support
A mature hanging basket tomato plant with moist soil can weigh 50 pounds or more. Couple wind with the weight of the container and it is easy to see how sturdy support is essential. Visit a local hardware department for wall anchors and hanging gear to support the hanging tomato plant.
Go for Tiny Tomatoes
The best tomato plants for hanging are varieties of cherry and grape tomatoes. These small-fruited plants hold up to container growing much better than large slicing tomatoes and their long, ropey vines trail over container edges. Here are 5 great hanging basket tomato plants.

How to Grow Hanging Tomato Plants
Tomatoes planted in traditional hanging baskets are planted in very much the same way you plant a pot of annual flowers. Fill the container with high-quality potting soil. Add a slow-release fertilizer—a fertilizer formulated for food crops is a great choice. Then add the tomato plant and water it well. Plan to water your tomato hanging basket daily and sometimes as frequently as twice a day in hot, dry conditions.
