Ajuga die off?
I have a patch of Ajuga that is dieing. last fall & this spring it looked like it was hell bent on world domination. it even covered 18" of my concrete driveway. i trimmed that off & transplanted it. about a month ago a 6" circle died off. since then it's begun to spread. it's had adequate but not too much water. 2 other patches are doing fine. any ideas??
