Companion planting is the age-old practice of planting different plants in close proximity so that they can help one another in some way. These plants complement each other by giving off scent or chemicals that repel harmful insects, or they may attract beneficial insects that are plant pollinators or predators to harmful insects. Some plants return micro-nutrients to the soil that can be used by other plants. This book describes more than 100 herbs, food plants and medicinal plants and their companions, with information on how, when and where to plant, harvest and use them.
It also contains recipes for natural fertilizers and insect sprays and information on how to use plants medicinally and in the home. Separate sections deal with useful weeds, natural sprays, mulches, natural fertilizers and other methods to improve soil.
