The pachysandra on one side of my front yard died gradually in the past two years, but the other side (last photo) is OK. I have an irrigation system, and water everywhere regularly. I live in Long Island, NY. I'm not sure about the reason, may be fungus. I'd like to know the cause and how to fix it. Thank you very much.

I also checked a few landscapers, but they are not sure about the reason, either. They suggest I try this, that, and something else if not work. They seem to be lack of the knowledge. Is the any company specialized in the plant diagnosis? Thank you.

















Good side without problem.

Probably volutella blight (fungus).
I would treat with an appropriate fungicide.

Is there any landscaping company good at diagnose and treatment? All landscapers I met did not seem to be clear about the cause, and I'm not confident that they can do the job well. Thank you.

I realize it's not a tree, but you might see if you can hire an arborist to take a look at it. They are specialists and have a lot more education than most landscapers. You'd just have to call and ask if that's a plant they're familiar with, and how much it would cost.

Is there any specialist for herbaceous plants I can hire? Thank you.
