The day after I last mowed my lawn, a small patch, approx 3 feet x 1 ft has developed where the end of the blades have grass have turned yellow or a yellowy brown colour.
The lawn was not in the greatest of conditions but I have cared for it over the summer & got a nice spread of lush green grass, where previously there were bare patches, dead grass & weeds. Whilst eliminating these it's ironic that where I have the patch of yellowy grass, this was previously a problem patch, so therefore not sure if related.
Last cut was in evening, just top grassing it, I didn't feed or water it after but it did rain overnight, no previous problems have occured.
Does anyone have any idea what this maybe & could it spread to other areas, especially those that were problematic
