Washtenaw County/Ann Arbor Master Composter

Master Composter Class description

Turn yard debris and produce scraps into something you can use to enrich your flowers, vegetables, and lawn. Discover the basics of home composting in this fun class taught by Master Composters eager to share their experience with you. After attending this course, passing the open book exam, and clocking 10 hours of hands-on community experience, you will become a certified Washtenaw County Master Composter. Class fee includes the Michigan Master Composting Manual.

The Washtenaw County Master Composter class  has been offered periodically through the Ann Arbor Public Schools Rec & Ed program. Class registration is available online at (search on "Master Composter").

    Need compost for gardens and landscapes? Go here for more information on municipal compost (certified by the U.S. Composting Council) and mulch sales locations. Free compost offers for Ann Arbor residents are available seasonally.

    Fall leaf management options reminder. Ann Arborites can choose to mulch their leaves on-site, or set paper bags and compost carts of leaves at the curb for weekly pickup,  or take advantage of free bulk leaf drop-off locations.  Please remember that the city no longer picks up loose leaves that are raked to the street. Info at

    May 9, 2011 — Recycle clean plastic flower pots and plant trays. Thanks to the July 2010 upgrade to the City of Ann Arbor’s single-stream recycling facility, an expanded range of plastic bottles, tubs, deli-trays, and cup-shapes can be put into recycling carts.  Acceptable plastic gardening containers include clean plastic pots used for holding plants, shrubs, and trees; clean trays that hold flats of plants (please discard the flimsy plant “cell packs”); and clean hanging planters (with the hangers removed and discarded). Press release attached (pdf).
