Dieback of Turkish Sedum
I have what seems to be a healthy groundcover of Turkish Sedum that turns grey during the summer in the densest part of the growth and seems to dieback. The plants are in full sun and good soil. I give them a moderate amount of water. Turkish sedum is supposedly relatively free of diseases or insect pests, but this dieback sure looks like a disease. Has anyone else seen this behavior in this otherwise lovely groundcover? Thanks.
