No-dig gardening, as the name suggests, involves minimal disruption to the soil. Instead of traditional tilling practices, which can harm soil structure and disrupt beneficial organisms, gardeners build their beds on top of existing soil. This method improves soil fertility, promotes earthworm activity, and retains moisture, creating an enriched environment for plants. It works by layering organic materials, such as compost, manure, straw, and cardboard, which decompose over time to provide nutrients for the plants.
