Plum Forest Farm

Plum Forest Farm grows great food for our community on Vashon Island. We do this by focusing on growing habitat (for our family, for wild and domestic plants and animals, and soil micro-organisms). Our varied seasonal vegetables and fruits have won us a reputation for delicious quality food. We sell our produce year-round through our farm stand, and also at the Vashon Farmer’s Market. Our eggs are available daily at the farm stand.

Joanne Jewell and Rob Peterson have been working in the fields of sustainable agriculture, organic gardening and pesticide reduction since the mid 1980s. Both have been garden coordinators at Seattle Tilth and are contributing authors of the Maritime Northwest Gardening Guide. We managed Brigit Croft Farm, a CSA in Snohomish from 1993-1998, which had 70 shares and also sold at the UDistrict Farmers Market.

We moved to Vashon Island in 1999 with our one year old daughter and gradually built the farm while focusing on parenting and keeping the mortgage paid with off-farm jobs. In late 2005 our second daughter was born and in 2008 we finally reached the point where we felt that the farm could produce enough income for Rob to discontinue the off farm job. In 2009 Joanne was able to let her off farm job go too.

In January 2026 Plum Forest Farm transitioned ownership to Olivia Mancl. Olivia has been working with us many years and has already been managing much of the farm work. She will now be in charge of all aspects of running the business. The farm is in her capable hands with our whole-hearted support.

Olivia is committed to the highest standards of caring for the life in and above the soil and also to producing the best food, which you will still find in the farmstand. If you have farmstandcredit you can continue using it just as you are used to. She is bringing her own creativity to her role and we are excited to see the ways she will make the farm even better. 

Our growing methods are based on integrating crops with livestock. In addition to providing eggs, meat, mowing, bug-eating, and other services, our Scottish Highland cattle and diverse flock of laying hens provide the manure that we compost with plant materials to create fertile soil. This soil lives on our flat to gently southward sloping crop field and produces vibrant produce. The farm is named for the enchanted old growth plum forest that we discovered under a wall of black berries when we came here in 1999.

We are gradually restoring a small forest on our land by cutting back invasive weeds and planting native plants. Most of our land is in pasture on which we practice rotational grazing. Using fencing, we allow our cows and chickens access to limited portions of the pasture, then move them frequently to fresh grass.
