Help me raise the best tomatoes!

[isuhunter]

You guys have convinced me to make my garden bigger, so I will be doing that. As I've been lurking around the site everyone has something they do that "helps" their tomatoes. Critique my "process" of growing tomatoes.

I plant in a garden which I keep slowly amending the soil and am starting my compost pile for future amendments.

I plant a variety of tomatoes, some heirlooms and hybrids, some from seed and some store/online purchased.

I typically mulch with grass clippings.

I water as I see needed. I use miracle grow tomato fertilizer.

I've never pruned.

I have rebar cages -- this year I'm going to go to the "florida weave" i think to save space.

Should I look at fish emulsion? Pruning? Different mulch?
