My ground covers are not doing well. I have mazus reptans between stepping stones. Last year, its first, I watered it a lot and it was quite happy as it spread between the stones. This year it is getting lots of dead brown matted patches which are spreading, even when getting plenty of moisture.

In another location, the lamium which had been beautiful, is gradually disappearing. Slugs did a lot of damage, but I can't blame them for the brown limp leaves that are obviously dying. The whole area is less than half of what it was a month ago. I'm suspecting that they've gotten too much moisture from all of the rain we got last week.

Any diagnosis for mazus or lamium gardeners?
