Tall, fast-growing evergreen screen?
Layout: North/South 3' wide planting area at the rear of my backyard, at grade with a 6' privacy fence on the east side, 4' drop to backyard level on west side. Nearly full midday/afternoon sun.
soil: clay, w/ a bit of sand.
background: Had three Loblolly pines spread 10' apart. They have died, one by one between the hottest part of summer and now. The needles have turned brown and fallen off.
question: I'd like to replace them with some sort of faster growing evergreen to provide screening from an upstairs window on the house to my east (behind the privacy fence). I need at least 15' of height. I'd like under the foliage to be open, for other mid-height shrubs between the trees (knock-out roses are there now). I'm looking at Spartan Juniper, Yoshino Japanese Cedar (will this grow here?) and Leyland Cypress. Any suggestions?
