Should a landscape company add fertilizer or soil amendments?

Yes—based on testing and plant needs, not guesswork. In Salt Lake and Davis Counties, many sites have alkaline, clay-heavy soils with low organic matter. A simple soil test pinpoints pH and nutrient gaps so your landscaper can choose the right amendments: compost to improve structure, sulfur to nudge pH, or targeted nutrients (nitrogen, phosphorus, iron) at safe rates. Ask for a one-page plan listing products, application rates, and timing for lawn, beds, and trees. Over-fertilizing wastes money and can burn roots or push weak growth. Under-fertilizing stalls establishment. Good practice pairs amendments with mulch, correct irrigation, and aeration where compaction exists. Have the company leave product labels and spreader settings with you, and request a spring/fall update so the plan evolves with your yard. Data-driven applications protect plants and waterways while improving vigor, color, and resilience.
