I have a horrible scrap ofgarden which wasconcreted over when we bought the house. We've taken up all the concrete, laid a small lawn and a small flower border (less than a metre wide- 70 cm? - and 7m long). The flower bed is slightly raised and made out of bought compost and topsoil.
The garden seems to have been made mainly out of scrag ends of soil and builder's rubble.
I have wanted to make my border a bit nocer by putting an edge on it and have chosen willow hurdlesas they were on offer and you can fill them up from the back. They arrived today and I got stuck into putting them in and I can't! You need three small loes about eight inches deep. On every patch I've tried I hit rocky nasty builders rubbly stuff that I can't dig out or get past about 6 inches down. If I am lucky I can get two out of three of the 'legs' in.
Is there any practical way I can drill though the horrible stones? Or m I going to have to put it actually into the border and so make the border even smaller. I don't actually think even this would work as I think the raised soil would eventually run out from underneath and the hurdles would bend and break.
I feel so disappointed! Can anyone think of a solution?
