Soil testing for healthier lawns, trees & gardens
Good care starts below the surface. Our soil-testing service helps you understand what your landscape needs before spending on fertilizer, lime or compost. We connect laboratory results with the plants, growing conditions and goals on your property.
Request Soil TestingFrom soil sample to a practical care plan
1. Review your landscape
We discuss weak growth, yellowing leaves, patchy turf or new planting plans, and look at moisture, drainage, shade and compaction. Symptoms can have several causes; adding fertilizer is not always the answer.
2. Collect representative samples
We plan sampling by area and plant use, keeping lawns, beds and problem spots separate where appropriate. Samples are collected and labeled for laboratory analysis, with the test scope agreed before work begins.
3. Explain the findings
We review the reported pH, nutrients and organic matter with you and relate them to the intended plants. Tests vary, so we explain what the selected analysis covers and when additional investigation may be useful.
4. Recommend the next steps
Your plan may include measured nutrient additions, pH correction, organic matter management or changes to watering and soil care. We discuss the scope and cost of any follow-on work separately and monitor how the landscape responds.
Healthy soil is alive
Soil is a habitat of mineral particles, organic matter, air, water and living organisms. Bacteria and fungi help break down residues and recycle nutrients. Many plants partner with mycorrhizal fungi that extend their access to soil resources, while roots release sugars that support soil life.
Organic matter supports this system and helps soil structure and moisture storage. Avoiding unnecessary compaction, maintaining appropriate mulch or plant cover, and managing irrigation help protect the habitat. More compost or a bottled microbe product is not automatically better; the site and existing soil matter.
Nutrients must be available—not just present
Roots absorb mineral nutrients dissolved in soil water. Nutrient availability changes with pH, moisture, temperature and root health. A plant can struggle even when the soil contains nutrients if its roots are waterlogged, compacted or unable to access them.
Plants use these elements to build tissues, capture sunlight, regulate water and reproduce. Both shortages and excesses can cause harm. Different plants have different needs, so one treatment should not be applied automatically across every bed and lawn.
The 17 essential elements plants need
Plants require nine macronutrients in larger amounts and eight micronutrients in trace amounts to grow and complete their life cycle. Small quantities do not mean small importance. Carbon, hydrogen and oxygen come mainly from air and water; the other 14 are mineral nutrients generally taken up through roots.
Macronutrients: nine essential elements
From air and water: Carbon (C), hydrogen (H) and oxygen (O) form much of the plant’s organic material.
Primary mineral nutrients: Nitrogen (N) supports proteins and leafy growth; phosphorus (P) supports energy transfer; potassium (K) helps regulate water and enzyme activity.
Secondary mineral nutrients: Calcium (Ca) supports cell walls; magnesium (Mg) is part of chlorophyll; sulfur (S) is used in amino acids.
Micronutrients: eight essential trace elements
Iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), chlorine (Cl) and nickel (Ni) support functions including photosynthesis, enzymes, growth and nutrient metabolism. Plants absorb chlorine as chloride. Trace-element additions require care because excess can be toxic.
What a soil test can—and cannot—tell you
Useful measurements for treatment decisions
A fertility test reports selected nutrient levels and soil pH; organic matter may be included or requested. Results help guide fertilizer and lime decisions. Nitrogen is often omitted from routine lawn and garden tests because its availability changes rapidly.
Not a complete diagnosis of every problem
A standard fertility test does not measure all 17 elements, count every microbe, identify every disease or prove soil is free of contaminants. Plant tissue analysis, salinity, contaminant or specialized biological testing may require separate arrangements. Drainage and compaction also need on-site assessment.
When should you test?
Before major planting or lawn renovation, when growth repeatedly disappoints, or before making substantial amendments. Retesting at an appropriate interval helps track changes; comparable areas and sampling conditions make results more useful. Tell us about recent fertilizer or lime applications when arranging a visit.
Better decisions for your property and local water
Testing helps avoid unnecessary nutrient applications and directs spending toward the actual limitation. Combined with good soil cover and water management, that reduces the risk of excess nutrients and sediment leaving the property.
Put the findings to work with Lawn Restoration, Lawn Maintenance, Plant Health Care or Planting & Gardens.
