Or if you want a tighter, denser, screen sooner - plant the spruce at about 8 ft. apart. Then, when your spruce start to touch each other, cut out every other one to let the remaining ones fill out. Just an option, since everyone's needs vary.As someone who has Norway spruce I planted 30 plus years ago. Spacing minimum 15 feet apart. Rows offset 25 feet back. If I had to do it again I would plant white pine on the outer row as they will easily outgrow the Norway but Norway do grow fast. Remember a 3 2 transplant seedling is a 5 year old tree going in the ground. Do not buy anything less than a 3 2 transplant. You will need to dig holes to plant them or use an augur. Always keep a 5 gallon bucket of water with you and throw the seedlings in the water to soak before you put them in the ground. Keep scissors to even the roots out and cut if needed. Do not j root the seedlings they will die. For those who gave you advice on switch grass it's a great idea. Your talking years for the growth to happen.
