"A thorough update and the introduction of new topics such as biodiversity and conservation has greatly enhanced this new edition: it is a 'must read' for all interested in horticulture and gardening." —John MacLeod, RHS Professor of Horticulture Most conventional gardening books concentrate on how and when to carry out horticultural tasks such as pruning, seed sowing and taking cuttings. This book is unique in explaining in straightforward terms some of the science that underlies these practices. It is principally a book of 'Why' – Why are plants green? Why should one cut beneath a leaf node when taking cuttings? Why do plants need so much water? But it also goes on to deal with the 'How', providing rationale behind the practical advice. The coverage is wide-ranging and comprehensive and includes the basic structure and functioning of garden plants, nomenclature, genetics and plant breeding, soil management, environmental factors affecting growth, methods of propagation and production, pest and disease control, post harvest management and storage, and conservation and sustainable horticulture. Now with full colour throughout, the second edition provides the reader with: Completely revised and updated chapters from the first edition, with new information and clearer focus on the topics Four new chapters, dealing with matters that have become of increasing concern since the first edition, namely: Diversity in the Plant World; Conservation and Sustainable Gardening; Gardens and the Natural World; and Gardens for Science Published on behalf of the Royal Horticultural Society, this book remains a key text for those sitting RHS examinations, particularly at levels 2 and 3; it will also appeal to gardeners, growers and scientists. Key Features Bestselling essential text for all horticulture students Edited and written by a group of highly regarded scientists Covers the scientific information of greatest importance to gardeners and horticulturists Jargon-free scientific explanations, a comprehensive glossary, and copious colour illustrations Royalties from the sale of this book go towards the charitable work of the RHS, promoting horticulture and helping gardeners. www.rhs.org.uk

Written in a clear and accessible style, Garden Practices and Their Science guides gardeners in the practical arts of plant husbandry and in their understanding of its underpinning principles. The author, Professor Geoff Dixon, is an acknowledged and internationally respected horticulturist and microbiologist; he intertwines these arts and principles carefully, expertly leading readers from one to the other. Achieving the manipulation of plant life is described in eight full-colour, well-illustrated chapters covering the growing of potatoes, bulb onions, legumes, small-seeded vegetables, soft fruit, bulbs and herbaceous ornamentals in great detail. Environmental factors controlling the successful husbandry of these crops is described in simple, non-technical language, increasing gardeners’ enjoyment and competence. Gardeners are also informed of the tools and equipment they require and their safe use. Also provided are a series of simple, straightforward tests identifying the aerial and soil environments beneficial for plant growth using readily accessible domestic tools. Discussions of very straightforward techniques for vegetative propagation conclude this book. Each chapter ends with a list of the gardening knowledge that has been gained by readers. The structure of this book fulfils a longstanding need for descriptions of practical skills integrated with the corresponding biological reactions of plants. Emphasis is placed on gardeners’ development of healthy soils, which encourage vigorous, active root systems capable of withstanding stresses—an aspect of gardening that rarely receives sufficient attention. Tailored for readers requiring clear and concise directions, this very practical book is an instruction manual directed at early-stage gardening learners. These include people of all ages and requirements such as new garden owners, allotment-holders, apprentices and students of basic levels in the Royal Horticultural Society’s or City & Guilds qualifications, career changers, community gardeners and those needing applied biological knowledge for GCSE examinations.

Companion planting has a long history of use by gardeners, but the explanation of why it works has been filled with folklore and conjecture. Plant Partners delivers a research-based rationale for this ever-popular growing technique, offering dozens of ways you can use scientifically tested plant partnerships to benefit your whole garden. Through an enhanced understanding of how plants interact with and influence each other, this guide suggests specific plant combinations that improve soil health and weed control, decrease pest damage, and increase biodiversity, resulting in real and measurable impacts in the garden.

Build healthy soil and grow better plants Robert Pavlis, a gardener for over four decades, debunks common soil myths, explores the rhizosphere, and provides a personalized soil fertility improvement program in this three-part popular science guidebook. Healthy soil means thriving plants. Yet untangling the soil food web and optimizing your soil health is beyond most gardeners, many of whom lack an in-depth knowledge of the soil ecosystem. Soil Science for Gardeners is an accessible, science-based guide to understanding soil fertility and, in particular, the rhizosphere – the thin layer of liquid and soil surrounding plant roots, so vital to plant health. Coverage includes: Soil biology and chemistry and how plants and soil interact Common soil health problems, including analyzing soil's fertility and plant nutrients The creation of a personalized plan for improving your soil fertility, including setting priorities and goals in a cost-effective, realistic time frame. Creating the optimal conditions for nature to do the heavy lifting of building soil fertility Written for the home gardener, market gardener, and micro-farmer, Soil Science for Gardeners is packed with information to help you grow thriving plants.

Sow the seeds of science and wonder and inspire the next generation of Earth stewards The School Garden Curriculum offers a unique and comprehensive framework, enabling students to grow their knowledge throughout the school year and build on it from kindergarten to eighth grade. From seasonal garden activities to inquiry projects and science-skill building, children will develop organic gardening solutions, a positive land ethic, systems thinking, and instincts for ecological stewardship. The world needs young people to grow into strong, scientifically literate environmental stewards. Learning gardens are great places to build this knowledge, yet until now there has been a lack of a multi-grade curriculum for school-wide teaching aimed at fostering a connection with the Earth. The book offers: A complete K-8 school-wide framework Over 200 engaging, weekly lesson plans – ready to share Place-based activities, immersive learning, and hands-on activities Integration of science, critical thinking, permaculture, and life skills Links to Next Generation Science Standards Further resources and information sources. A model and guide for all educators, The School Garden Curriculum is the complete package for any school wishing to use ecosystem perspectives, science, and permaculture to connect children to positive land ethics, personal responsibility, and wonder, while building vital lifelong skills.
