Farming Citrus in Placer County: Rooted in History, Thriving in the Foothills

Citrus farming in Placer County, once known as the "fruit basket of the nation," is experiencing a revitalization, thanks to the county’s ideal growing conditions and its deep agricultural roots. From the early Welsh settlers who planted the first mandarins to today’s thriving groves, citrus trees, particularly mandarins like Satsuma, have become a cornerstone of local farming.

When it comes to growing citrus in Placer County, site selection is key. Citrus trees need full sun—ideally 8 hours a day—to thrive and produce quality fruit. With the foothills offering a mild climate, a southwest-facing slope is the perfect spot to plant. Soil drainage is just as important, and while Placer County’s soil is generally suitable, ensuring a steady water supply is vital, especially during the hot summer months.

Mandarins, which are the most popular citrus in the area, require proper rootstock, with trifoliate rootstocks being a great option for cold tolerance and disease resistance. When planting, aim for spring (March-April), and make sure the graft union is above ground level. Water well during the first year, but avoid overwatering as it can lead to root rot. Pruning is important for maintaining tree health and fruit quality, but it should be done wisely to allow enough light and air circulation to reduce disease risk.

Citrus trees in Placer County don’t just produce fruit; they provide an opportunity for connection to the land, sustainable agriculture, and a piece of history. Growing citrus here is more than just farming—it’s about fostering a connection to the environment, cultivating food sovereignty, and honoring the legacy of those who first planted in these fertile soils.

If you’re looking to start a citrus farm or simply want to add a few trees to your homestead, Placer County offers the perfect climate and rich history to grow citrus that’s as vibrant as its legacy.
