Reply #3: I've grown them for years so here's what you do:

For containers: you'll need about a 5 gallon pot per plant, that's about 14 inches across the top. I use clay for edibles instead of plastic. Choose a variety that is good for containers such as Husky, or a patio tomato. Full sun is fine, unless you live in the desert like me...so morning sun, afternoon shade will be OK. Or, cover with cheesecloth or shade cloth to avoid scalding the fruit. I put in granular fertilizer when I plant, then use foliar feeding (Miracle Grow or equivalent) every couple of weeks. Plants in pots will dry out quickly, esp. in the wind...I water every day in the AM and sometimes later if it's very windy.

As for the ones along the fence: determinates will stop growing at a certain size, but they can still be large. Indeterminates just keep vining. It really doesn't make a difference except for how much vining you have room for. Get a book or search on the internet if you want to prune them to keep them manageable. You just have to learn what to take off. Staking will keep fruit cleaner, but you can just let them run which helps shade the fruit. It depends on what your situation is; again a basic internet how-to will help you make that decision.

Just be aware that tomatoes can't really set fruit above about 90 degrees. Shade cloth will drop the temp. 10-15 degrees and helps if this is the problem...

If you are getting lots of greenery but no fruit...you are probably feeding them too much.

Also, try to water at the base instead of with a hose from overhead. You'll have fewer problems with some of those nasty leaf and systemic diseases that occur with too much dampness....
