RICK. Thank you for all the info. I will try several of these methods. I did add some compost I had been making in a bin and it wasn't quite composted. So that probably is the culprit. Sounds like I may need to remove some soil and replace. And will try some bark on top as you suggested. Today I misted with chamomile tea. If that doesn't slow it down I will try your peroxide solution next.
Thanks very much. Carol.
