Hate joining a forum and starting off with a question but...
Zoysia lawn in S.C. - in the back yard I am starting to see these small piles of dirt or something. Up close they are little balls stocked on top. When I rake them up there is a half dollar dead spot and the ground is somewhat compacted.
Lawn has been good this year (weed/fungus standpoint). Follow the Carolina Fresh farms program for the most part with healthy doses of milorganite throughout the year.
Had some sevin dust granules so I put some down yesterday along with the normal fungicide treatment.
