With his wife, Sue, he has run Crûg Farm as a plant nursery since 1991, winning gold at Chelsea, amongst other awards. Every year the couple undertake plant-hunting trips to bring back exotic but hardy plants ensuring that their nursery is a UK Mecca for plantaholics.
They are happy to bring pre-ordered plants to the meeting.
Since 2012 he has been the Director of the Castle Howard Arboretum Trust. It was established in 1997 as a partnership between the Royal Botanic Gardens at Kew and Castle Howard Estate and administers the Yorkshire Arboretum. He is a respected gardener, botanist and author who has written or edited several books including “New Trees: Recent Introductions to Cultivation” with Ross Bayton. His gardening interests are very broad but his specialities include bulbs, ferns and African plants, his particular interest being the origin of plants and he has travelled widely to see them growing in their natural habitat.
