It would be helpful to know what USDA Planting Zone you are in for starters but the short answer is yes and no. There are diehards on both sides of the fence about trimming tomato plants. Personally I am caught somewhere in between. I pinch off the lowest branches to the ground so that they don’t get splashed from underneath. Last year I had heirlooms that were growing so tall that I honestly topped them off so the wouldn’t be taller than 8 feet. I trimmed twice over the season and cut off a total of 5 feet from the plant. That means the plant would have grown 13 feet tall!
The tomatoes themselves don’t need to be in the direct sunlight per se. For starters, make sure you have at least 2-3 tomato plants in the same area. When you see the blooms begin to mature and become fully open, lightly tap them (the blooms) with your finger. This helps them pollinate and will result in more blooms becoming tomatoes.
Best of luck and if you have more questions please feel free to ask!

]]>I’m growing two of my heirloom tomatoes upside down this year too, as well as a pepper plant (not sure which one yet) because my new place in Atlanta has a great space for it – the rafters of a second floor deck on the back of the house.
Look forward to seeing how your project progresses!
