If the tree is in a cardboard-like container, place it in the hole and cut away as much as you can, but it is not necessary to remove all of the pot. If the tree root is wrapped in burlap, remove as much of the burlap as possible. To prevent a tree from strangling as it grows, it’s crucial to cut off or pull away any twine or wire wrapped around the trunk.
If the roots are tangled or pot-bound, loosen them with your fingers, a cultivator claw or even slice through them with the sharp edge of a spade to break them up and encourage them to grow outward.
If you are planting a bare-root plant, first soak the roots in a bucket of water for eight to 24 hours to hydrate them thoroughly. For best results, add root stimulator to the water to help plants overcome transplant shock. Trusted brands such as Vigoro carry a wide selection available in-store. Prepare the planting hole as you would for a container tree. Then make a rough cone shape of dirt at the bottom of the hole, and spread the roots over the cone.
