Kew Gardens is a convenient station for visitors to the Royal Botanic Gardens, Kew.
In addition to its various botanical treasures, Kew Gardens is also the site of Europe's largest compost heap, which produces 3,500 tonnes of mulch per year for use in the gardens and for sale to the public. As well as woody, leafy and grassy waste generated in the gardens, the compost heap consumes 50 cubic metres per week of horse manure and stable bedding "donated" by the Royal Horse Artillery Barracks.
