Hello, I have planted Roman Chamomile (the perennial, not the German annual variety) as a ground cover among roses on either side of a path. Some of the plants on one side of the plant have centers that have begun to wilt and die (see photo). On the other, the plants are still thriving and spreading. I planted and have been caring for both sides exactly the same way, naturally, and both sides have been watered regularly (I live in Los Angeles). Could I be overwatering? Or do they appear diseased? Would much appreciate any suggestions.
