K&J Orchards


Kalayada Ammatya and her two daughters, Aomboon (“Boonie”) and Onanong (“Ona”), along with 12 full-time and 30-40 seasonal workers. Aomboon’s husband, Tim, also works on the farm, and members of their extended family help on the farm and with sales at farmers markets.


104 acres in Winters, about 67 miles from the Ferry Plaza Farmers Market.

Farm History

Wife-and-husband team Kalayada Ammatya and James Beutel (“K” and “J”) started farming in 1982. James was a professor of pomology, the branch of horticulture that is concerned with the study and cultivation of fruit. He grew up on an avocado orchard in Orange. Kalayada was born and raised in Bangkok, Thailand, and is a registered nurse.

The family believes in using natural growing methods and maximizing the use of the sun. They prune most of their fruit trees in the summer after harvest to provide the most sun exposure to each tree, which then stimulates growth and, they believe, leads to sweeter fruit.




The farm’s Yolo loam is amended with cover crops, manure, mowed sod, and organic fertilizers.

Water Use

Micro sprinklers, drip, and flood irrigation.

Weed Control

Mowing and discing. Minimal synthetic herbicides are used to prevent weeds from competing with trees for nutrients.

Pest Management

Integrated Pest Management including pheremone disruption. Minimal pesticides are also used. K&J uses antibiotics in the spring to treat and prevent fire blight in their Asian pear orchards.

Fun Fact

K&J Orchards has a long fruit season that begins with the first cherry harvest in spring and culminates in pear and apple harvests in autumn.
