lts has been said that it does bear increased yields if you do compare to other plants that are grown the "normal" way in containers.

l also read that there is an increased in air circulation to the leaves. Disease and pest are avoided since there is no contact with garden soil

There has been a number of discussions on them here but since the search engine is currently down I can't pull them together for you to review.

Mixed results as I recall the discussions but nothing rave about them. Like many of these "gadget approaches to gardening" they never seem to be quite as wonderful as the TV commercials would have us believe. ;)

Hopefully the SE will be back soon and then you can find the discussions using "upside down tomatoes".

Well, It works in Australia (Ha, Ha) They're on the bottom of the globe, see, so..Seriously I bought some bags from thompson morgan As the Brits say they were very DEAR. I washed the soil out when I watered. There were plants but no fruit on the toms;a few annual flowers zinnas,but not as nice as a potted plant. Of course I have friends of friends who rave about great successes but no first person success stories or proof.

Since you did also ask "why it isn't great" ...

I always wonder if anyone else is going to say this, but guess not, so maybe I'm alone in feeling this way. But gosh darn, to me those upside down pots just look so unnatural and unattractive. You're left looking at a plain ugly empty looking pot or pail at eye level. No leaves cascading over the edge to camoflauge or soften it. Maybe if there were some wave petunias or trailing lobelia planted on top that would hide the pot? But then they'd be competing with the tomato for nutrients.
Aesthetically, I much prefer my plants right side up as nature intended. But each to his/her own.

I grew two last year in the same mix as other container toms but upside down.

I will not be bothering with this again.

More work, less production.

If it were the only way I could grow toms, I'd think about it but other than that, I found it a complete waste and had wanted it to work.

I am new to gardening, but i am growing 1 upside down jelly bean hybrid, it's healthy, but is growing a lot slower then the rest. I just used a empty gallon jug. I cut the bottom out and hung it upside down. then place the seedling and filled with soil.

I purchased 2 topsy turvy's this year just to give it a shot, I figured, what the hell? right? I'm gonna try a Roma and a husky cherry red. We'll see how it works!

I'm going to try a cherry, beefsteak and roma varieties in them this year. I have never used them before so it's quiote experimental. From all the discussions I've read it seems the best idea is to avoid it if you have good solid alternatives, and if not then try it for yourself. There are so many varying results and all of that has to do with the conditions each one is grown under. I believe I can be successful and I'm not going into it looking for a cake walk. I'm used to watering small containers once or twice a day so it wo't be a huge step for me to take.

Here's a link to the previous discussions if you want to read them.
