Aaron's love of gardening dates to his New Zealand childhood, working in his grandfather's vegetable garden. Arriving in England in 1996 to volunteer at Great Dixter, he earned a Diploma in Horticulture at the Royal Botanic Gardens, Kew, then spent two years at Jerusalem Botanical Gardens, where he is still a trustee. Bertelsen returned to Great Dixter in 2005 and is regularly invited to speak about gardening at events worldwide. This spring, his garden-to-table recipes will be published in The Great Dixter Cookbook.
