The curator's role at RHS Garden Bridgewater is to lead on the development and delivery of all aspects of horticulture, in line with the garden masterplan and working with the estates team on the built and garden infrastructure.
Chilton-Jones joined Dorothy Clive in 2008. He was previously at Trentham and the National Trust's Nyman, Morden Hall and The Vyne gardens.
During the development phase at Bridgewater there will be four horticulturists, one administrator and subsequently building to three garden managers (and teams) and one administrator.
After the garden opens, the role will be to ensure that excellent standards of horticulture and the visual displays in the gardens "amaze, delight and engage visitors throughout the seasons," the RHS said.
The horticultural team will grow to about 30 staff, six training places and a team of volunteers post-opening.
Chilton-Jones will also plan and deliver the initial horticultural project phases and facilitate aspects of community outreach programmes.
The role is also to represent RHS Garden Bridgewater through engagement with interested parties such as the local community and planning authorities and to undertake media work to promote the garden including potential television work recording the development of the garden, and to take control and management of an agreed curatorial budget for the garden.
The role was advertised at £45,000 a year.
At the other four RHS gardens, Matthew Pottage is curator of RHS Wisley, and Robert Brett is curator at Hyde Hall. Both were appointed in 2015. Harlow Carr curator is Paul Cook, appointed in 2013 and Rosemoor curator is Jon Webster, appointed in 2010.
