In the last few years the herb garden has been maintained by a dedicated group of volunteers. In 2009 students from Lewes Old Grammar school as part of their community activity for the Duke of Edinburgh's Award planted a new hedge on the southern boundary of the herb garden.
In 2010, as part of the Heritage Lottery project, the herb garden was extended by over two metres to the north to provide a new raised flower bed and extended pathway around the garden. A interpretation panel gives historical information about monastic herb gardens and the herbs grown within. The new bench and the new herb garden are dedicated by the Town Council and Lewes Priory Trust to the memory of Hilary Black who loved the garden and spent many hours working in it.
