After a bit of deliberation, he decided he was going to re-turf it and headed off to the garden centre with the dog. (He was taking her for a walk nearby). When he got back he started clearing the existing turf ready to lay the new turf which had cost just over £30. The dog, who was glued to his side most of the day had to go out and help of course. Most of the time she was digging, but I only managed to catch her sat here as he was raking the ground over and levelling it.
The next day, (Sunday) he finished the job and laid the new turf. I'm afraid I didn't get a picture of what it looked like before the makeover, but here's a picture of how it looks now.
Thank you OH, you did a great job.
