Want To Learn About Composting?

These 2-hour workshops are $10 per family (only one member need register) and they will provide you with everything you need to start composting. If you begin in spring, you will have finished compost to spread in the fall.



What You Will Learn

You will learn the "Greens Browns Water Air" approach to maintaining a compost pile. This approach uses simple scientific principles to guide your composting experience and is flexible to fit your lifestyle. You'll feel empowered to compost almost anything.

You'll know what not to compost and why, and where to use caution.

You'll see a dozen different compost systems at work, and be able to use the tools before you buy anything, to find what works best for you.

You'll learn how our climate affects our soil and get some tips for composting year-round. Yes, even in January!

You'll learn how compost contributes to turning our silty-clay soil into deep, rich topsoil and how other simple gardening strategies will build soil faster.

New Thanksgiving Event (So new it doesn’t have a name yet!)

Monday October 14 at 1pm

Bring your best compost, leaf mould, castings, or soil. We’ll mix our materials to create a microbe- and nutrient-rich blend, and then you’ll take home as much as you brought. Use it to inoculate your compost pile or garden.

Healthy soil is full of tiny living things that help plants grow. Damaged soil can lack many beneficial organisms. This event is about sharing the life in our soil and helping each other grow.

By sharing microbes we increase biodiversity and help heal chemical damage caused by our misunderstanding of soil over many decades.

Compost like a pro with simple tips from the City's Compost Doctors. They'll help you understand the process so you can easily create a product that will help you reach your gardening goals.

"Carbon Farming” is a horticultural solution to the Greenhouse effect.  If just one percent of humans became carbon farmers all the CO2 emissions produced in a year would be drawn down into the soil. Learn how you can make a few simple changes in your house and garden to start farming carbon this spring.

Turn Clay into Soil!  Learn the natural processes involved in Soil Building so you can improve your weedy, compacted, poorly growing garden.  Healthy plants grow best where soil building techniques improve depth, tilth and aeration.
