Horticulture at Level 2. Units 5 - 8

This is your essential guide to RHS level 2 Principles of Plant Growth and Development, Units 5 - 8.

This is the second edition, updated for the 2026 RHS syllabus changes.

Comprehensively covering Unit 5 - 8 content for the second exam, this guide follows the RHS syllabus order and is perfect for accompanying lectures, distance learning materials, or even to facilitate self-taught study. The guide is specific and targeted directly to the RHS level 2, Principles of Plant Growth and Development course. Information is written in concise chunks to maximise clarity, and links between parts of the syllabus are woven in to help you answer the harder exam questions. The guide is packed with images and diagrams to illustrate content and improve your recall of key information. There’s even advice on how best to prepare for the exams.

This book is an invaluable resource for anyone studying RHS level 2, written by an RHS trained gardener and experienced horticultural teacher.
