Indoor Composting: Make and Take Home a Bokashi Bucket

Don’t throw away those scraps...up to 20% of household trash can be composted! The bokashi bucket system, which can be used year-round, is quick, convenient and produces no household odors. In this hands-on session, construct and learn to maintain an indoor composting system capable of decomposing food and house plant trimmings for a family of four. In a space-saving bokashi system, effective microorganisms transform all types of kitchen waste into a nutrient-rich soil amendment. All equipment, materials and handouts provided and included in fee. You’ll create a working indoor composting system in the form of a bokashi bucket. Class offered in partnership with the Missouri Botanical Garden Earthways Center. Registration deadline 9/1. No refunds after this date. Course meets the curriculum requirements for the Master Naturalist program.
