I think the relationship between Fergus and Christopher Lloyd was really unique and you could say that before Fergus, Christo was the Head gardener! Joking aside, I don't remember though we went to Dixter from way back before Fergus joined the garden. Some of Christopher Lloyd's long term friends like Graham Gough and Kemal Mehdi (who used to lecture at Hadlow and lived near to Dixter) would surely know.
