Public Works

We encourage you to attend a free workshop to improve your lawn/garden, conserve water, and reduce waste. No reservations needed. Workshops are about 1.5 hours and are held at libraries, parks, and other venues. Purchase compost bins at a discount after each workshop. Or join our free webinars.

We teach two workshop curriculums:

★ Beginner: learn the basic techniques of backyard composting, worm composting, water-wise gardening, grasscycling, and edible gardening.

★ Advanced:

learn the fundamental principles for drought-tolerant landscaping, integrated pest management, and organic gardening.
