This is the one or norway spruce .You want evergreen ,because it blocks the sound also. Norway grow about 3 ft a year. ThuJa`s green giants grow faster.
Leyland cypress don`t live long. How old are you ?White pine ,Norway spruce, Thuja green giant is the way I would go. I have 30 acres and I planted Autumn olive on my one side. Nothing kills them ,they grow fast,smell good and the birds..turkeys love the berries. They are supposed to be invasive,but I haven`t noticed after 8 yrs. I plant about 150 things a year. Probably planted a thousand things in my 9 yrs here. Look up pine grove nursery in pa. if you want great prices on seedlings,it`s a friend and his prices are the best.
