Q.My 6 Year Old Arbovitae Trees Dying
Hillside landscape with rock cover. Has 10 trees, 12’ tall that have done fine for 6-7. This year 2 have gradually begun to brown and eventually die. Once they start water and fertilizer don’t help. I am going to try a soil test next. Any suggestions would help.

It could be from winter desiccation or disease. A soil test is a good idea.
