The planting hole for each tree should be three times the diameter of the rootball (e.g., ~30”-wide for a 5–gallon container) – centered on the planting location (regardless of slope) – and almost as deep as the root ball is high (e.g., ~10”-deep for a 5–gallon container), with a level bottom and scored sides.
Note that the depth of the planting hole is measured at the exact planting location in relation to the existing grade at that spot, even if the ground is sloped and/or undulating. Obviously, pre-existing grading problems should be fixed before planting any trees in the area and all tree locations should be selected with proper drainage in mind.
