"It has plenty of foliage but has yet to put out a single blossom."

I have observed the same on a balcony in my apartment building...

I saw a prototype for something like the topsy turvy in a 70s-era Mother Earth News article, it's nothing new. In my experience it works better with cherry tomatoes, especially if you position a pot of the same variety underneath so they can cross-pollinate. Planting a shallow-rooted flower like lobelia on top helps slow the evaporation of water and leeching out of fertilizers. I found them cute but not spectacular beyond the initial impression.

Im kinda over my topsy turvy and want my tomato in the gorund. Im TOTALLY new to gardening though so i dont know if i can transplant it safely now? I have no flowers, no tomatoes. The plant has grown to about... 2 feet probably if the branches weren't all curled up... Can I take it out and stick it in the ground and still get tomatoes, or should I just leave it alone and hope for the best?

Now this is where having to grow everything in containers probably would give me an edge over people who have only ever grown things in the ground when trying this for the first time. The directions probably say to just add potting soil and water. Now, because I have to use potting soil, I know that it is high in nitrogen because even the organic potting soil is designed to grow lush-foliaged houseplants. When you grow tomatoes in potting soil you need to balance out the nitrogen by adding some bone meal for phosphorus and either greensand or kelp meal for potassium. I actually use a product by E.B. Stone Organics called Sul Po Mag, which is some mineral that contains a lot of sulfur and magnesium as well as potassium instead of greensand or kelp meal, but I water with a very weak solution of liquid seaweed for the micronutrients.
