Farm History

David was raised in Los Angeles but rejected the urban life early on. He attended the UC Santa Cruz Farm and Garden Apprenticeship Program in 1994 then spent the majority of his 20s traveling and working on farms internationally and around the US. In 2000, at the age of 29, he started County Line Harvest.


Marin Certified Organic Agriculture (MOCA) since 2002


County Line is surrounded by pastureland, making chicken and cow manure easy to come by for composting. The farm also incorporates a fair amount of green plant  material back into the soil. County Line is in full production year-round, but around 25% of the land is cover cropped at any given time.

Water Use

Overhead irrigation from an on-farm reservoir.

Weed Control

Tractor cultivation, hand-weeding and gentle disking.

Pest Management

Floating row covers protect the crops from pests. The cold nights and windy conditions, along with crop diversity and nearby wildlife habitat, also help keep pest populations low.

Fun Fact

When the current owners of the ranch were kids, there was a monkey living on the property.
