Cryptomeria japonica branches dying
I planted 2 of these in late November (zone 7, coastal DE). New site, new topsoil, etc. We had a more severe winter than normal, and one of the trees shows several dead branches. I fertilized with Holly Tone in late March. A couple of weeks ago I pruned the dead branches (wiping the shears with rubbing alcohol after each cut) and burnt them. Less than 2 weeks later, more branches are starting to show the same symptoms.
ps- can't get the photo to rotate, so the tree is lying on its side...
Any idea what could be causing this? They are beautiful, 10' tall, and an anchor to my landscape plan. I am unfamiliar with these as we just moved into the area from a more northern climate. Any help/ suggestions would be appreciated!
