Please help me save my shrubs
Hello, I am desperate for help. A few days ago, I had a french drain dug across the width of my home to take care of a major drainage problem. As such, the trench was dug about 2 feet in front of my line of 7 shrubs. Although I can't recall the name variety of shrub, I have babied them since I planted them as 1-ft tall plants about 5 years ago.
The day after the digging, I noticed a ring of dead leaves around each shrub. I watered them thinking it was either shock from the digging or perhaps lack of water, or both. The ditch did not appear to sever any roots, at least none that I could see of any size. Since then the dead leaf areas have expanded.
Here are some pictures. Please help me save my shrubs. I have no idea what to do.
