Farmstead snapshot
Hazelnut + truffle orchard
A resilient dual planting where each hazelnut tree is managed as a host for Périgord truffles and long-term soil health.
Hazelnuts
Cold-hardy European hazelnuts selected for disease resistance, productivity, and flavor. Tree layout is designed for stable root zones, runoff control, and fungal health—each tree chosen and managed as a host for Périgord truffles.
Périgord truffles
Tuber melanosporum grows beneath the hazelnuts, forming a long-term mycorrhizal partnership with the trees.
Puget Sound shell inputs
Crushed oyster shells from Puget Sound provide annual liming, keeping soils alkaline enough for truffles while supporting nut yield and resilience.
Regenerative discipline
Orchard care is informed by mycology, permaculture practice, and shell-based mineral amendments, with an emphasis on soil biology and long-term resilience.
Symbiosis & codependence
The hazelnuts send carbohydrates to the fungi in exchange for nutrients and water, anchoring the fungal network around stable root systems.
Truffle fungi extend the effective reach of the roots, pulling in minerals and moisture, and buffering the orchard against stress.
Annual additions of crushed oyster shells help maintain slightly alkaline soils, supporting truffle development while keeping hazelnuts productive.
Trees, fungi, and shells together create a sea-influenced terroir that ties Puget Sound's shellfish economy to perennial tree crops.
Farmstead vision
The orchard is a long-term project centered on soil health and circularity—careful spacing, biological monitoring, and shell-based amendments keep the trees and fungi thriving together.
As the plantings mature, the farm is being shaped as a place for intimate gatherings, small workshops, and seasonal harvest experiences that connect guests to the orchard's rhythms.
Outputs become inputs: oyster shells from Puget Sound are reintroduced to the land, supporting hazelnut and truffle production while closing loops between coastal resources and perennial crops.
About & contact
Briny Grove Farmstead is a future 10-acre hazelnut and Périgord truffle orchard in Washington State, built around sea-to-soil circularity. The farm will transform waste oyster shells from Puget Sound into a key soil amendment, tying local shellfish economies to perennial tree crops and long-term soil health.
We’re in the establishment phase now—laying out orchard blocks, designing event and education spaces, and building partnerships around circular, shell-based soil programs.
