Choose at least a 5-6' tree grown to nursery standards.
Select a site with enough room for roots and branches to reach full size. Avoid overhead and underground utilities.
Prepare a planting area as deep as the root ball and 3-5 times its diameter by loosening the soil. Dig a hole in the middle of the area and set the root ball even with the ground level.
Use water to settle soil and remove air pockets in planting area.
Stake the tree to flex with the wind only if tree is unable to stand up to wind.
