With organic gardening, it’s all about soil microbes. What we do to enrich our soils with organic matter and humus helps to feed this population of invisible organisms. Their presence enhances fertility to help plants grow healthier with a stronger root and immune system. To truly understand how important this microbe-plant relationship is to your food garden, read Jeff Lowenfels’ outstanding book: Teaming with Microbes (Timber Press). It is the modern gardener’s guide to the soil food web, what it is, how to protect it and why it’s essential to use organic fertilizers, amendments and potting soils that support this vital population.
