About Compost

What is Compost?

Compost, also called humus, is a dark, crumbly, brown or black, earthy-smelling form of decomposing organic matter. In a few weeks to a few months, once-living materials that are put in a bin or pile, and get adequate air and moisture, will transform into nutrient-rich soil.

Why Should I Make Compost?

Composting is a practical and convenient way to recycle yard debris, such as leaves, twigs, grass clippings, most weeds, and dead houseplants into a valuable resource. If you have a garden, a lawn, trees, shrubs or even planter boxes, you have a use for compost. When used as mulch, this free soil additive promotes weed and erosion control, protects plant roots from sun and wind damage, conserves water, and reduces soil diseases. When absorbed into loose or sandy soils, it increases water retention; it also aids drainage in clay or other heavy soils.

What Can I Compost?

Yard debris, such as leaves, grass clippings, weeds, and the remains of garden plants make excellent compost. Chipped wood scraps can also be composted or mulched. Vegetable scraps are compostable, but food scraps such as meat scraps, bones, fatty foods, and dairy products should not be composted due to the potential for bacterial growth.

How Can I Use Compost?

Compost can be used to enrich the flower and vegetable garden, to improve the soil around trees and shrubs, as a soil amendment for house plants and planter boxes, and when screened, as part of a seed-starting mix or lawn top-dressing. Compost acts as a natural fertilizer by returning nutrients, such as phosphorus, potassium, nitrogen, and many trace minerals, to the soil. These nutrients are all to be released slowly over 1-2 years for optimal plant growth and health.

Annually, the City of St. Louis generates approximately 20,000 tons of yard waste, which is composted for use as an alternative soil. The State of Missouri and the State of Illinois passed laws prohibiting yard waste from being disposed of in the landfill, in an effort to conserve landfill space. Yard debris is a highly valuable material that can easily be converted into a product useful for improving your garden, landscaping, and lawn. By mulching and composting yard debris at home, you can save money spent on mulches, fertilizers, herbicides, pesticides, and soil amendments. Mulching and composting at home also reduces the amount of time you spend watering because they preserve the moisture content in your lawn or garden.

    City of St. Louis Collection Program

    For those residents who don't have the physical ability, space, or use for mulching or composting their yard waste, the City of St. Louis operates a separate weekly collection service for yard waste during the spring, summer, and fall. Residents with alley dumpsters should place yard waste in separate dumpsters marked "Yard Waste Only." Residents with smaller roll-out carts receive a separate collection for yard waste on Wednesday of each week. Residents may bundle limbs in six foot lengths and place them out for the monthly bulk pick up. The Refuse Division will also accept one pick-up truck load of yard waste each month from residents at either the north or south transfer station (with proof of residency). Visit the Refuse Division's Yard Waste page or call 353-8877 for more information.

    City residents with large amounts of yard waste can dispose of it once a month at the Forestry Division's Compost Section at 560 Terminal Row (located off of Hall Street) in the Baden area (zip code 63147). The site is open from 7 a.m. to 3 p.m. Monday through Saturday, except holidays. It is closed in January and February. The site will accept tree limbs under six inches in diameter, shrubs and leaves. Grass clippings will not be accepted. Residents will be allowed to dump one pick-up truck load per month (also with proof of residency). Commercial haulers are prohibited.

    Free Compost Pick-up Locations

    The Forestry Division Compost Section takes the yard waste generated by St. Louis City residents and the Forestry Division and recycles it for use as compost and mulch, which is available free to all city residents. Pick up materials at Forestry Division processing facilities located at Carondelet Park (east side) or 560 Terminal Row (just east of Hall Street). Additionally, they also stock boxes with compost and wood chips in gardens located at Chippewa and Oregon, 9th and Barton, and Vandeventer and West Belle.
