Soil Seed WaterMade in Central Iowa from local yard waste, Grow Gold Compost® promotes healthy, lush plant growth without the use of chemical fertilizers.

  • Grow Gold Compost® is created on a nine-acre site, located at Metro Park East Landfill in Mitchellville, from yard waste collected through the Compost It! program in Central Iowa. Yard waste is ground once it arrives to our facility, then turned and maintained for four to nine months as it decomposes. Once finished, compost is screened to no larger than 1/2 inch and is tested for quality by the U.S. Composting Council. No artificial chemical supplements are added to the compost at any point during Metro Waste Authority’s process.

  • Once you’ve determined the project that you’ll use compost for according to the below recipes, you’ll know the appropriate compost application depth for your project and be able to find out how many cubic feet of compost you’ll need to purchase by entering the information in here:

    • Potting Soil
      • Blend one-part compost with one-part sand and one-part garden soil.
    • Flowers + Vegetable Gardens
      • Incorporate 1-2 inches of compost in the top 3-5 inches of soil a few weeks prior to planting. Reapply compost to soil every two years.
    • New Lawns
      • Incorporate 1-2 inches of compost to a depth of 6-8 inches into existing soil before seeding or sodding.
    • Established lawn maintenance
      • Aerate lawn thoroughly in spring and/or fall. Then, to top dress or over-seed, apply 1/4-1/2 inch of compost.
    • Trees + Shrubs
      • Dig a hole the same depth as the root ball and at least twice as wide. Mix one-part compost with three parts soil saved from the planting hole. Place the tree or shrub in the hole and apply amended soil around the root ball.
