About San Diego County Agriculture
San Diego county has over 5,000 farms, more than any other county in the United States. 69% of those are between 1-9 acres and though the median size farm is just 4 acres, our county's farmers rank number one in both California and the nation in the production value of nursery, floriculture and avocados.
Agriculture here covers 242,554 acres and is a key contributor to San Diego's economy, along with defense, manufacturing, tourism and biotechnology. Our varied topography creates a wide fluctuation of microclimates that allows for nearly 30 different types of vegetation communities. This diversity allows for San Diego to grow over 200 different agricultural commodities from strawberries along the coast, apples in the mountain areas, to palm trees in the desert.
