The society's first garden was in Kensington, from 1818 to 1822. In 1820 the society leased some of Hugh Ronalds' nursery ground at Little Ealing to set up an experimental garden, but the next year part of the Duke of Devonshire's estate at Chiswick was obtained. In 1823 it employed Joseph Paxton there. From 1827 the society held fêtes at the Chiswick garden, and from 1833, shows with competitive classes for flowers and vegetables. In 1861 the RHS (as it had now become) developed a new garden at South Kensington on land leased from the Royal Commission for the Exhibition of 1851 (the Science Museum, Imperial College and the Royal College of Music now occupy the site), but it was closed in 1882. The Chiswick garden was maintained until 1903–1904, by which time Sir Thomas Hanbury had bought the garden at Wisley and presented it to the RHS.
