We planted 10 Japanese shrubs along the front of our house this fall. Now, all but 4 are showing signs of dying. We have done what the nursery told us: water deeply, every so many days. Aka we water about 1 hour per 3 days. But now 6 of them are showing major signs of dying. My mother mentioned 'wounding' the root ball, which we didn't really do when we planted. So DH went back and 'wounded' the dying ones on one side. We've seen no difference in the last 3 weeks though. I'm afraid they'll all die. Of course, our nursery says we can return them for a half off discount, but we'd rather these guys pull through. Any ideas? We completely tilled down at least two feet before planting, and added brand new dirt to the beds before planting. We water on a schedule in correspondence with our nursery's suggestions. Just stumped, and sad. My grandmother passed away this summer and left us a little money, so these are 'her' shrubs, and I really want them to thrive and do her green thumb justice.
