The green staff have just begun work on restoring some greens back to their correct size.
They have put some white dotted lines on the greens and aprons. These are in place to signify the edge of the green etc where they have grown in size over the last two seasons. When you mow on slopes the mower will drift slightly and over time this adds to the m² area. We are not making the greens smaller we're putting them back into shape to fit the irrigation patterns again.
You will notice in the photo attached that the green looks quite a bit smaller but if you pay attention to the apron it is not full size in this area, it has crept up the bank to the putting green.
