It will till better if its bushhoged first, If it hasn't been turned in a few years, you may want to consider having it ploughed and disced. much easer on your back and shoulders. It will be real weedy this year, but next year it will be great.leigha said:This will be our first vegetable garden. Right now, the weeds, grass, whatever is at our shoulders. Do we bushhog it down and till all the top layer under or bushhog it down and use a shovel to cut off the top layer of sod? Thanks.
