I hear you all groan. I'm slightly ashamed to post this but here goes. I have two window boxes on my upstairs windows at home so not all that easy to water or maintain. I'd like some, wait for it... fake box hedges or something. I know I should have real but I am lazy and have killed everything i've put in so far. i just want them to look tidy (look at me justifying my atrocious choice!) Anyone know where i could get something half decent?
