From Shovel to Screen

Composting has always been at the heart of the Mendocino Coast Botanical Gardens. It is an essential source of nutrients that keeps our garden thriving. What began as a humble effort with a small mechanical compost shredder has evolved into something far more efficient (and far less back-breaking).

That first machine, donated by MCBG Horticulturist Jim Celeri, required loading shovel by shovel and produced soil that was a little too refined—like powdered sugar, when what we really needed was flour.

Next came what we affectionately called the “Poorman’s Compost Sifter.” Built by MCBG Maintenance Manager, Pete Baker, from repurposed materials, it was a masterpiece of creativity and thrift. Pete discovered an old rock screen in the maintenance yard and fashioned a sturdy frame from redwood beams salvaged during bridge reconstruction along Fern Creek Trail.

This ingenious contraption allowed us to use the bobcat to pour soil over the screen and “shake it out.” The shaking, however, came courtesy of a brave staff member repeatedly pressing a pedal attached to a forklift. After about 32 hours of sifting, we had our compost but also a serious case of leg cramps.

Now, thanks to the generosity of JoJo Barker, Karen Guthrie, Marilyn LeRoy, Liz O’Hara, Katie Wheeler, and one anonymous donor, our composting operation has stepped into the modern era. Their support made possible the purchase of a new electric motorized soil screener, a dream come true for our horticulture team.

This new equipment is more than a time-saver; it is a game-changer. Staff can now create custom soil blends for our retail nursery, propagation projects, and nationally recognized Heath & Heather Collections, and we will save money by reducing the need to purchase specialty mixes. Even our trusty forklift will enjoy a longer life, no longer rattled by the demands of the old sifter.

Our donors have helped us move from shovels to sustainability, proving once again that innovation and a little community support can grow from the ground up. Learn more and consider contributing to the success of this coastal gem.
