Hi,

I recently moved into our property and am starting to renovate a garden that has pretty much been left fallow. Straight off the bat, I am coming from zero expertise and knowledge of gardening, but I appear to have 'caught the bug'. I want to grow a wildlife area at the back of the garden, where previously there was just shingle, and whilst clearing the shingle, which I thought was laying on earth, was actually on a bed of concrete. What I want to know is, if I were to raise three areas by covering the concrete with earth, would I be able to plant wild grasses and flowers in them? If so, what depth does it need to be? Is there anything I need to do to add nutrients? I guess the main issue is drainage...

I appreciate all your help.

Cheers
Luke
