Students from a Byron school didn’t spend Wednesday, one of their last days of the academic year, inside a classroom. Instead, they were outdoors on a sunny day learning how a local farm produces and processes organic fruits.

The 34 students at Mountain House School, a two-room school on Mountain House Road, went on a field trip, sponsored by the Byron-Bethany Irrigation District, that took them to the Frog Hollow Farm near Brentwood.

Frog Hollow is a 143-acre agricultural enterprise — mostly orchards — that specializes in growing, shipping and processing organic fruits.

The students saw the orchards where cherries, apricots, peaches, pears, plums and pluots are grown without use of pesticides or herbicides. They also saw processing facilities where the fruits are prepared for shipment.

Sarah Coddington, a partner in Frog Hollow Farm, told the students that the farm’s goal is to get organically certified fruit from tree to table within 48 hours.

“We make sure our fruit is tree-ripened and packaged for shipping in a matter of hours,” she said. “We ship to food markets, farmers markets and to online customers.”

Coddington said fruit not meeting cosmetic standards is made into conserve, which is used to make pies and other products.

During their tour of Frog Hollow’s orchards, the students saw apricots being dried naturally without the use of sulfur.

Coddington said Frog Hollow operates a store and bake shop in the San Francisco Ferry Building, where many customers get their first taste of organically grown products.

After touring the organic farm, the students were treated to a barbecue lunch at the Byron-Bethany Irrigation District headquarters on Bruns Road near Byron.
