Hi Ben,

Is your lawn Winter Green Couch? During winter couch grass tends to loose some colour although winter green retains more colour than most. During the warmer months did you notice any caterpillars such as cut worm or armyworm present. These caterpillars attack the lawn during January and February. African black beetles are also a common pest of lawns in WA. Check the leaf blades for any spots which will indicate a disease such as Spring Dead Spot. This disease generally leaves a much larger patch. If you wish to de-thatch the grass in the future you can hire a de-thatching or scarifier or you could also use a garden fork to help aerate the soil. You may not need to do this for some time as the lawn is new.
