Tomato plants grown upside down tend to be stronger and produce a more abundant crop, along with allowing gardeners with limited space to have fresh tomatoes all summer long. When choosing plants for growing in upside down containers, look for small fruited tomatoes and determinate varieties, which only grow so large and are easier to control. Tomatoes do well in all growing zones as long as you wait until after the last frost to hang the upside down tomatoes outside.
Small Fry tomatoes produce clusters of small fruit that grow to about 1 inch in diameter, making this a perfect variety for an upside down container.

Water daily so the soil stays moist and never dries out completely. The tomatoes mature in 70 to 75 days after planting and are ready to harvest when uniformly red in color.

Patio hybrid tomatoes are a dwarf tomato plant specifically grown to be planted in containers, including upside down containers. The tomatoes grow to about 4 oz. and yield a firm red fruit, ideal for slicing. Add compost to the soil before planting to increase the nutrients and allow for a well-draining soil, and hang in a location that receives full sun all day. Water your Patio hybrid tomato at least once a day to keep the soil from drying out. Harvest the tomatoes about 65 days after planting, when they are completely red and give slightly when gently squeezed.
