I've dug a shallow grave, what am I doing? In over my head..

Thanks! Good stuff! Habitat_gardener & janezee, I read about that, but read tomatoes have roots 2-5 ft deep & very wide so I worried about putting anything like wood down (guess newspaper deteriorates).

Been trying to clear some of the Bermuda grass that is my entire lawn (except for the clover). Fighting a loosing battle. Hoped clearing 1.5' for each plant & mulch would be enough for tom plants to get roots down, so they wouldn't be strangled when the BG storms back in..? (Had no clue this stuff is so bad & w/ the concrete dirt, the proper tools might be a sledgehammer/wedge/blowtorch). May be wasting my time if it will just strangle em though. Pic below is at a weird angle, shorter than it is, but that's what I've got done. Didn't get enough dirt to raise it up much, dunno.. All that brown looks clear, but only 1/2 foot is, rest is just covered in dirt.

-meadowck, I agree about the Milorganite, I was given this half a bucket of 'magic mix' from someone at the US botanic gardens who came up w/ it. No clue why she would use human sludge when other things have the same effect. Have seen it do wonders for flowering plants, but don't feel good about putting it on food plants.. Have a bag of tomato-tone & seen a bunch of recipes on here, dunno which would be cheaper but those are better probably. Oh & I just cried a little picturing having an arbor covered in tomatoes like that 'tomato tree' photo in epcot Well, when I'm a home owner instead of renter maybe!
--Containers, agreed, are necessary. My be the only choice now. Drip emitters I keep hearing about would be a necessity. Still have some giant pots, now to pay for the mix... I hear that 5:1:1 recipe's good.. Man good weather today.. off to back out there.
