Healthy soil acts as a reservoir, storing and slowly releasing moisture to plant roots. Building rich, organic soil through composting, mulching, and reduced tillage boosts its water-holding capacity, decreases erosion, and minimizes runoff. Strategies like deep-rooted plantings improve soil structure, while organic amendments promote microbial life that further supports water retention. The result is a garden that is not only drought-resilient but also teeming with life, thriving with less need for supplemental watering.
