Topsy Turvy Tomato Planter Update - 3 Months

I had to move my Topsy Turvy Tomato Planter to hang in the tree because it was getting too long for it's previous home. It was nearly dragging the ground.







My tomato plant has beautiful green leaves on it, but no flowers right now. And obviously no tomatoes.



I am beginning to think this experiment is going to be a failure. What do you think?
