News and Announcements

Composting and Soil Fertility Workshop, November 12, 8:30 am to 5:00 pm

Continuous soil amending in the high desert is an imperative for local gardeners. Soil fertility is enhanced with the regular addition of organic matter. Home composting and related techniques are ways of recycling plant nutrients back into the soil. Through presentation, discussion, and demonstration the workshop will offer some useful take-home information that any gardener can immediately put into practice. Cost of the all-day workshop is $25. Location, class details, and registration info are available here.

Learn About Bokashi Composting

Have you heard about Bokashi composting? It's a method developed in Japan that is inexpensive, easy, takes up little space, has no smells, doesn't attract pests, and requires no turning. The method makes it hard to find an excuse not to compost your kitchen waste! You can compost all the kitchen scraps you normally compost as well as meat, bones, and oily things. Jill Van Nortwick recently gave a talk to BERNCO master composters about Bokashi composting. Check out these powerpoint slides from the talk. Or, if you prefer, here is a PDF copy of the slides. The slides include a video about Bokashi composting. The video is made by a commercial company but keep in mind that you can do Bokashi composting in ordinary buckets.
