Soils and soil additives are essential in the landscape because they create the foundation for healthy plant growth. Quality soil provides proper structure, nutrients, and drainage, allowing roots to establish and absorb water efficiently. Soil additives improve existing soil by correcting compaction, enhancing aeration, increasing organic matter, and balancing moisture retention. Together, soils and amendments help plants grow stronger, resist stress, and perform better long term while improving overall soil health and landscape success.
