Hi, Any advice appreciated on why a lawn laid a year ago ( Rolawn Medallion Turf) is not growing vigorously and is now showing distinct yellowing of some blades as can be seen in the photo. The soil was prepared to 150mm, fine compost added and fertilizer top dressed prior to laying the turf. This season a liquid lawn feed was applied in early spring and then Miracle Grow applied a little later. Any advice on what to do to try and improve the lawn . Many thanks ..
