When not working on royal engagements or at home, Kate Middleton enjoys spending time with her children outdoors, particularly at the RHS Back To Nature Garden - a woodland garden in London. Getting her children involved, Kate, who recently announced that she is being treated for cancer, likes to take Prince George, Princess Charlotte and Prince Louis to help decorate the garden by gathering moss, leaves, and twigs. Last year, she even backed the RHS's campaign to promote gardening in schools, a scheme which aim is to bring nature into the lives of youngsters.
