New garden - how to excavate and prepare site?
Hi folks,
I finally took the plunge and started digging to discover the cause of my drainage problems. Surprise, surprise - it's heavily compacted soil on top of solid clay ... lots of clay. I haven't got the patience to wait for the effects of soil improvement techniques, so I've decided to start from scratch and just excavate the whole site. What I need to know is this: 1) ... What depth should I dig to? (I have a digger). 2) ... What type of aggregate and organic materials do I need? 3) ... What depths should each material be, and in what order? My best guess is (top to bottom): Compost Topsoil Sharp sand Chips (granite?) Hardcore Is this correct? What depths for each? Is the materials and depths different for lawn areas than for borders? I've already excavated a test area about 12'x3' and discovered all kinds of builders rubbish, including massive lumps of concrete and plastic bags, etc. Both front and back gardens are flat; the back has full sun; the front is shaded. I'm in the N/E coastal area of Scotland (clay country), and it's wet and windy. Thanks, [H]omer |
