What is this yellow patch with fine mesh webs on the edge of my kikuyu lawn?

Hi Nigel,

There is a mite that attacks couch grass called couchgrass mite but I am not aware that it attacks kikuyu. From your description, it does sound like it is a mite because of the webbing you are seeing. Mites are so tiny that it is difficult to see them with the naked eye. Kikuyu can suffer with a disease called kikuyu yellows but this usually occurs during wet/hot weather. This fungus causes the roots to rot causing the grass to yellow off and become quite thin in patches.. There is no specific treatment but improving the drainage will help. It might be worthwhile seeking some help from a turf specialist to properly diagnose the problem.
