The fourth edition of this popular title has been given a completely new look, but it remains the same practical illustrated guide that is a must-have for all gardeners. The text has been updated to incorporate more indigenous species, locally bred hybrids, and waterwise plants, in keeping with changing trends that recognize the importance of gardening in harmony with the natural environment.

The bulk of the book comprises directories that describe over 2000 plants (trees, shrubs, perennials, annuals, creepers, bulbs, grasses and roses) with each entry accompanied by symbols that depict the ideal growing conditions, such as water and sun requirements, hardiness to frost, and whether the plant is deciduous, evergreen or flowering.

A brief introduction covers garden planning and design, maintenance, and how to deal with pests and diseases. The book concludes with a handy list of plants, grouped according to their suitability for particular circumstances, such as drought-tolerance, growing in containers, in full or partial shade, or to provide flowers for the vase.

This book shows you how to identify, tackle and solve both pests and diseases naturally in your organic edible garden. The book is divided into 5 easily navigable chapters:

1. Prevention

Learn how to create and maintain a balanced garden to help plants naturally withstand pests and diseases, including detailed methods of preventing problems before they start.

2. Solutions

If problems do occur, this chapter provides effective natural solutions. It also traces the rise and impact of chemical pesticides in agriculture, and the shift back to safer organic alternatives. Included is a comprehensive A–Z of natural solutions.

3. Host plants

This chapter provides details of edible plants (vegetables, herbs, grains, fruit and nuts) and potential pests or diseases that can affect them, with a focus on ideal growing conditions to prevent problems.

4. Pests

This chapter is a guide to commonly found pests, organised within their biological orders, with separate sections on larger and opportunistic pests. Each entry features photographs and descriptions to help with identification, plus information about their size, host plants, targeted plant parts, damage symptoms and natural enemies.

5. Diseases

Diseases are divided into three sections – Bacterial, Fungal and Viral – with detailed methods for prevention and solutions, plus plenty of photographs for easy identification. Included is information on hosts, symptoms, how each disease spreads and optimum conditions.

There are also quick guides at the start of both the Pests and Diseases sections to help identify common problems, a glossary and detailed index for further reference
