Pile of Bricks

I've been spending more time in the garden and if the weather holds it might even begin to look tidy. I would still like to encourage wildness so have left a patch of nettles and thistles. 
The pile of bricks is in the next garden but beside the common access to the pond, which has a pair of resident swans and occasional visiting geese and ducks.
Apart from containing the exuberant grass I need to tame some wild blackberry, prune the trees and find plants that like the old Belfast sink.
