26 acres (the orchard is planted on 9 acres) in Oroville, about 149 miles from the Ferry Plaza Farmers Market.

Farm History

Carl created Woodleaf Farm in the Sierra Foothills in 1980. The farm’s clay loam is augmented with 2 to 4 tons of green waste compost per acre per year, plus a grass/clover permanent living mulch. The farm is home to 2,200 fruit trees, wild turkeys, working farm cats, and many beneficial biological control insects and birds.
At Woodleaf Farm, teaching sustainable farming and lifestyle is vital. A longtime soils consultant, Carl has been instrumental in the California Certified Organic Farmers (CCOF) Going Organic Project mentoring conventional farmers as they transition to organic practices. He also teaches organic farming and gardening classes.

The farm’s clay loam is augmented with six tons of compost per acre per year, planted with grass and clover cover crops, amended with kelp, yucca extract, and molasses, and mineralized with gypsum, limestone, and soft rock phosphate based on soil analysis.

Water Use

Water is sourced from a small lake above the farm. Gravity moves the water from the lake to sprinklers in the orchard.

Weed Control

Carl hand-hoes and mows all of the weeds that crop up at his farm.

Pest Management

The farm maintains habitat for beneficial insects, employs crop rotation, and sprays peach trees at bloom time with Bacillus thuringiensis, a naturally occurring bacteria that kills certain insect larvae. Rock dust, sulfur, and copper are also used to control plant diseases, and soil is kept as “alive” as possible.

Fun Fact

100% of the electrical needs of Woodleaf Farm are met by an 8.1 kilowatt solar array installed in 2006.
