Bishopthorpe Bowling Club End-of-Season Maintenance On Friday 18 September 2015, our annual end-of-season maintenance work was carried out by Richard Topping of TopNic Groundcare: Deep scarifying and sweeping up the debris. Thatch removed by scarifying - getting better - much less than last year. Six tonnes of top-dressing to be spread. Over-seeding done - top dressing in progress. Drag-matting to re-level the surface. Finally, application of autumn fertiliser. Two weeks later - looking really good!
