I want to grow a hedge behind a 500mm high old stone wall, to give some privacy to my garden and to act as a shelter belt for my planned fruit/veg garden. Can you please suggest a quick growing evergreen (not laylandes!) – that will withstand windy conditions. The location has full sun for most of the day. Also, I’m on a budget so nothing TOO extravagent! Also, its a cottage garden. OK thats it thanks!
