Adding amendments to the soil when backfilling can cause the tree roots to
stay in that area. They will tend to not grow out farther than the hole dug
to plant it. At best mix a little fertilizer in with the backfill and
proceed as Jim explained. This is what the recent research is saying. Good
luck, Lekoma
