I did not need to fight with tree roots of trees I wanted to keep alive. but you could till close as you can until you start hitting roots and then you could use cardboard to help smother up to/around tree and tilled area and cover with soil to grow above roots,,
I might smother the grass around tree[to help stop it from spreading back into garden] but instead of using soil close to tree use wood chips about 3 feet out around trunk, if you go this route it might be a good place to use plastic on top of cardboard and under wood chips so in a couple years the grass is not coming up threw chips.
do you use kiddy pool to grow in? lol how about cutting hole in middle big enough to go around peach tree and a cut to open from hole in center to outside edge to wrap around tree then plant something inside pool you want to control spread of ? thinking mint? would still use cardboard under it to smother grass out
