the growth of plants is all to do with the way in which chemical substances maintain and control life. If we start with an understanding of this, we’re well on the way to meeting the needs of plants and creating a flourishing, beautiful and productive garden.

A basic understanding of science can teach us much about our plants and gardens and turn us into better gardeners. Once we know how plants are constructed, it is easier to work out how they will grow and flourish. An understanding of the structure of a good soil gives clues as to how to improve our own. Mary Pratt’s compelling explanations breathe life into scientific principles and illustrate the effects of their application in the garden. Practical Science for Gardeners begins by looking at what plants need to survive and how these fundamental scientific facts are at the heart of good plant care. A chapter on seeds and germination encourages keen propagators to refine their techniques while further discussion of soil, pests and diseases adds to the skills of all gardeners. The final section of the book takes a close look at biodiversity and unravels the mysteries of genetic engineering and plant naming. Packed full of tips about how to apply science to achieve healthier plants and better gardens, this informative and entertaining book will stimulate experimentation and encourage gardeners to review their gardening practices in the light of their new-found knowledge.
