I realize there are probably some other gardening threads around here but I didn't want to sift through them in order to find an answer to a more specific question so I apologize. I have a roughly 80'x15' spot in my back yard that previously was a garden several home owners ago. It's raised slightly with some landscaping timbers about 5 to 6". It got completely overgrown with weeds along with other plants that someone had put in there at some time. I can't identify what was exactly was in there but it wasn't anything that was at all pleasing to the eye but I know it was just standard yard weeds. I sprinkled a little gas around in there and lit the thing up knowing that is likely the best way to get rid of all that and minimize regrowth of unwanted plants. I realize that may have been my first mistake but it is what it is. What I'm wondering is what and how much I need to till into the soil for maximum plant growth. I plan to plan cucumbers, zucinni, several different vairieties of tomatoes both large and small, green beans and maybe take a 4th of it and section it off for a small stawberry bed. Any and all good advice would be more than welcome. TIA
