The house and its Hatton Fruit Garden are owned by East Malling Trust - of which East Malling Research (EMR) is a subsidiary, and are are opening to the public for the thirtieth consecutive year in aid of the National Gardens Scheme.
Staff from EMR will be on hand on the day to show how the fruit trees in the fruit garden - formerly the walled kitchen gardens of Bradbourne House - have been trained and pruned to produce cordons, espaliers, goblets, pyramids, fans, arches, crowns, le bateau and arcure forms.
Visitors will also be able to see the garden's 47 varieties of apple, 28 varieties of pear and individuals of medlar, nectarine, peach and fig will be on display in the garden - which was originally planted in 1945 and inspired by the fruit plantings in Louis XIV kitchen garden at Versailles.
It was created as a memorial to the art of tree training and pruning and as a source of information for gardening enthusiasts.
The concept was to establish a fruit garden with trees planted at appropriate spacings to show the economic use of ground, without over-crowding.
Although selective tree removal and replanting has occurred, many examples of the original planting remain.
