With over 1300 types of fruit, and the most accessible collection of apples, pears and plums in the UK, it has been described as a "living library" of fruit cultivators. Wisley is the RHS centre near Woking in Surrey. It holds a special collection of gooseberries, currants, rhubarb, figs and other soft fruit. Wisley has harnessed its horticultural knowledge, science and nature, to create incredible garden and orchards that are known world-wide. For an apple tree to fruit well, it needs to be pollinated; for pollination to be succesful, each tree needs to be neighboured by other trees that flower at the same time. For that reason, many of the apple trees were re-planted in the 1950's and arranged according to their season of ripening. The fruit trees are managed organically and interplanted with cornfield annuals to attract beneficial insects.
