What are some ways to encourage soil regeneration in gardens without relying on commercial products?

ANSWER: To regenerate soil naturally, practice no-till gardening to maintain soil structure and minimize disruption. Add organic matter like compost to improve fertility and water retention. Plant cover crops such as clover or legumes to fix nitrogen and protect soil. Use mulch to suppress weeds and retain moisture. Rotate crops to prevent nutrient depletion and disease buildup. Encourage a rich microbial and earthworm population by minimizing chemical use and maintaining a diverse garden ecosystem. These methods foster resilient, nutrient-rich soil without commercial products.
