Ground preparation for lawn turf
I have just joined this forum hoping to learn more about gardening in general, but for starters, ground preparation for lawn turf.
I had hoped that I could search the threads to read other forum members approaches, but I can't seem to find the search button. Maybe that will be my first reply back!
Anyway, our project involves extending the rear of the house and some landscaping work in our small garden (8x20 mtr).
Sometime in the past there was some raised beds supported by stone walls around the perimeter and into the centre. The walls and beds have now gone, but the foundations are still there. And boy, they are very tough. They must be a foot deep and made from brilliant concrete. I have used an electric hammer chisel to chip away, but only managed to get about 4 inch off in one area!
We are planning to level all this area and lay some lawn turf for spring 2017, so my question is, is 4 inch enough depth for the turf to grow without shading over the remains of the foundations?
Thanks in advance.
