Want To Learn About Composting?

These 2-hour workshops provide you with everything you need to start composting. If you begin in spring, you will have finished compost to spread in the fall.

We also have soil-focused presentations for experienced gardeners to help you reach your food-growing and soil-building goals.



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.
