What is Compost?

A sustainable, recycled, nutrient-rich soil amendment resulting from controlled decomposition of organic material.

How do we make compost?

Olympic Garden Compost is produced using local residential and commercial yard waste, prunings, grass clippings, manure, as well as commercially collected food waste. We use a state-of-the-art, computer controlled temperature and air system to ensure the compost is heated to correct temperatures to effectively destroy weed seeds and pathogens, as well as reduce persistent herbicides and pesticides in the compost.

LoaderOur compost is produced and regularly tested to ensure compliance with Washington State regulations, as well as the US Composting Council (USCC). We are STA Certified with the US Composting Council, which means we produce our compost properly and test it regularly according to their guidelines. This assures our customers that they are getting a quality compost that is made properly.

Benefits of Compost

  • Improves soil structure, porosity, and density, providing a better environment for plant roots.
  • Adds significant quantities of organic matter to soil.
  • Reduces erosion and runoff.
  • Improves water and nutrient holding capacity of soil
  • Supports beneficial soil microbes that recycle nutrients and protects plants from disease.
  • Saves time and money by reducing the need for water, fertilizer and pesticides.
  • As a mulch, compost limits weed growth, reduces evaporation, and keeps soil temperature even.

Application Rates

  • New Lawns: 1" to 2" of compost mixed 8" deep into existing soil.
  • Established Lawns: Spread a 1/2" to 1" layer of compost and rake in once per year, spring or fall. Mixing grass seed with compost encourages new growth.
  • New Landscape Beds: 2" to 4" of compost mixed with 8" to 12" deep
  • Established Landscape Beds: Mulch with 2" to 3" of compost. Leave a 3" border around plant stems and trunks
  • New Annual Flower or Vegetable Gardens: 2" to 4" of compost mixed in 8" to 10" deep
  • Established Annual Flower or Vegetable Gardens: 1" to 2" of compost mixed in 2-6" deep yearly.

Yardage calculation

  • Step 1: Determine the square footage of your project.
  • Step 2: Determine the depth in inches to fit your needs.
  • Step 3: Multiply Step 1 x Step 2 x 0.0031 = cubic yards.
For Example, an 6' x 10' planter box = 60 square feet
If you need your soil 8" deep, multiply those together with 0.0031:
60' x 8" x 0.0031 = 1.488 cubic yards, or about 1 ½ cubic yards of soil.
Or use the calculator on the right.
