This great website was conceived by two keen gardeners who organised Open Gardens in their own village for a number of years. It is now run voluntarily by them with the help of a few committed gardening friends. Find Ashwell at Home in their National Directory
Supporting Town and Village Open Gardens
They aim to publicise town or village event and are neither a large company nor a corporate body - just some amateur gardeners who occasionally swap the potting shed for the keyboard.
