I am planning on converting a patch of my gardens into a play area for the children's sand pit, swing and climbing frame. The area is between the house and a large beech hedge so gets very little light, meaning it mostly grows ivy and moss and a few other weeds. I'm contemplating rubber chippings as I've heard they are better than wood chippings. Does anyone have any experience? Tips/advice, Or a better suggestion? It needs to be relatively cheap as is a fair sized area to cover.
