Some plants thrive in each others’ company. They offer protection from bugs and disease, provide shade and enrich the earth with nutrients.  And, some plants do not. The A-Z of Companion Planting explains the theory and the practice. It looks at its usage historically and brings the practice up to date with today’s gardening techniques and our desire for chemical-free vegetables. The author guides you through which crops, herbs, grasses and fruits can be planted together (and equally important, which must not) to make sure that you get the very best crop with the highest yields – and naturally!   Combined with a handy, easy to use diagnostic table and clear, easy to understand line drawings.
