Planting Your Evergreen
Your first task is to dig the hole. Dig the hole deep and wide. Loosen the soil adequately for the roots to extend easily. Evergreens are generally shallow rooted. A good rule of thumb (green thumb) is to dig 2 to 4 times the width of the root ball and at least a foot deep.
Plant the evergreen, adjust and lightly tamp the soil level. Be sure the root ball is level with the surrounding soil level. Use the existing the soil you dug out to the hole, smoothing and lightly firming the soil. Water the soil until it is well soaked.
Apply mulch in a 2 to 4 inch thick layer several inches wider than the widest part of the plant. Avoid mulch contact with the evergreen trunk.
Care of Newly Planted Evergreens
Apply enough water to encourage good root development. Slow soak the evergreen each week. Your purpose is to soak the root ball and surrounding ground. This will encourage root growth.
