Soil Amendments

What This Service Involves

Healthy soil is the foundation of every successful public landscape, and Western Washington's compacted, often-poor soils benefit greatly from amendment. We test and condition soil in beds and turf areas, adding organic matter, adjusting pH, and improving structure and drainage. Better soil grows healthier plants that resist disease and drought, cutting replacement and irrigation costs over time. Amendments are matched to soil-test results and to each site's plant palette and use.

Benefits

Healthier plants that resist disease and drought; improved drainage and reduced compaction; lower long-term replacement and watering costs; amendments guided by soil-test data; better establishment for new and renovated plantings

Our Process

1) Collect and analyze soil samples from target areas; 2) Recommend amendments based on test results; 3) Incorporate organic matter and adjust pH and structure; 4) Document applications and monitor plant response

What Affects the Cost

Area and depth requiring amendment; soil-test results and materials needed; incorporation method and equipment access; volume of organic material and compost; whether work ties into a larger renovation

Best Time of Year

Soil amendment works best in fall and early spring when soils are workable and cool-season rains help materials integrate before the growing season.
