Hi All, this has been going on for a while and some of the lawn has died completely, other parts look like the photos, but I suspect will go the same way. I've treated the whole lawn with the Bayer Lawn Disease Control product and some areas have improved but not all, as the photo's show. I do occasionally lightly feed with Growmore during the summer but last year I tried the product sold on QVC by a well know gardener. Its probably coincidence because the grass did look good for a while but thought you should know being as I'm asking for advice. Anyone any idea what the problem could be please? I've attached a couple of photos. Thanks.
