Large areas of dried out, sparse grass seemingly not having enough water but also brown rough patches where the grass is thick and green. Fertilized with Scotts Turrfbuilder, Miloganite and a bi-monthly treatment by 'Zoysia Green' (fungus and moth). Watered 20 minutes per station, starting at 12 am and finishing at 5 am (15 stations). Grass cut by contractor; could this be disease brought in from other lawns and other species of grass on 'dirty blades'? We live inland in central Florida, hot and humid at the moment.
