start off by gettin plain soil and flush them when you put them in new soil because Miracle Grow has time released ferts and you dont want that. even if it might not be miracle grow i would still put them in soil that you know what it is so if you have any n, p or k defficentys(sp) then you will know y and if they have to much of anything you will know y. good luck and change the soillllll lol
