Our internationally renowned signature course

Covers training in the more serious aspects of horticultural practice and planting design. One day a week, the course is taught over three terms and begins annually late September.  Horticulture lectures at the School are led by Edward Flint, Ben Pope and Derry Watkins with termly instruction on drawing up professional planting plans, helping students obtain work after the course.  Practical sessions are held at Sandhill Farm House near Petersfield, home of Rosemary Alexander and at Arundel Castle under the guidance of the head gardener Martin Duncan.  Sandhill tutorial sessions are with Laurence Evans who trained at Chelsea Physic Garden and Tina Woodward. Exclusive visits to private gardens are an integral part of the course.
