Book excerpt: Essential reading for all studying horticulture and keen gardeners. This clear introduction to the principles underlying the practical applications of horticulture opens up the excitement of growing plants and garden development without readers wading through complex information. Written by a team of highly motivated and experienced horticultural tutors, the text supports the newly restructured RHS Level 2 qualifications with related Level 3 topics in boxes and signposting to Level 4 topics, together with other horticultural qualifications at these levels. Full colour images tied closely to the text and practical case study boxes inspire readers by making topics relevant to their own horticultural experiences. A comprehensive glossary helps build confidence in the use of classical horticulture language as well as new developing terms, and end-of-chapter questions encourage readers to apply what they have learnt. Extensive online supporting material includes mind maps showing the relationship of topics and aiding students in revision.
