I prefer using a water soluble non-organic for a couple of reeasons. First, it will contact all of the roots and remain in the pores of the soil grits. Second, at least in my area, organics will attract creatures that can be destructive to my trees. Birds, mice, squirrels, and various insects will start poking around in the soil and disturb the roots or knock the trees over. Others may not have this issue.
