Broadly determinate (bush) tomatoes are best for upside down tomato growing. The alternative indeterminate tomatoes can just keep growing and be a little unmanageable. Determinate have their height, bushiness and growing season more fixed in their DNA.
Some people have used indeterminate tomato varieties in inverted growing but it requires carefully pruning.
Some determinate tomatoes varieties that have worked for others include Tomato tumbling tom red or yellow, tomato tumbler, tomato yellow pigmy and tomato garden pearl. If you can grown any other varieties upside down please let us know in the comments below.

Very cool! I don’t know much about growing tomatoes so I’ll be checking your blog out again. I have a few pots of tomatoes I put up on my deck railing without any upright support. I was thinking they would eventually fall over and trail down over the railing.
