simonc Thx. Mine is rectangular a half-polygon finish on one side. Spent some time developing this from barren lawn. I made the mistake of not top dressing to level out an uneven bumpy surface.
It is in a decent shape now, although it is not densely grown; as a result, a lot of moss has taken over since last season. We have now eliminated the moss, raked and aerated it. Will be top dressing and over seeding this week.
Plan to lay MDPE pipes just outside the edges, one each on all 4 corners,
one additional on 3 sides and nothing at the centre and on the semi-circle side.
The area is about 90 sq M.
