I was in one of the traps at a garden centre the other day, and was particularly disappointed at the lack of graffiti, especially as you could be rather inventive.
i was thinking of compiing a selection along the lines of;-
'looking for wild thyme?'
'sow your seeds in my front / rear border'
'I need some old mans beard in my front hedge'
'strim my undergrowth'
Andy, H, Rex etc, take the floor.
