Welcome to Tilth Alliance


By Liza Burke, Marketing and Communications Director

Tilth Alliance was born in 2016 when Tilth Producers, Cascade Harvest Coalition and Seattle Tilth realized that the most effective way to get more people growing and eating healthy food is uniting farmers, eaters, gardeners, cooks and environmental advocates to champion a sustainable food culture. Now a more inclusive and impactful organization, an introduction is in order…

We’re Tilth Alliance, nice to meet you!

Our vision is simple. At Tilth Alliance we want everyone to eat well every day. We’re nurturing a culture where nutritious food is front and center, and available to everyone, and recognize this vision is not possible without  successful regional farmers and a healthy planet.

It’s no secret that the ways we currently produce food is creating all sorts of problems – for people’s health, for farmers and for the environment. Tilth Alliance is changing the way food is grown, distributed and eaten.

We use farms, gardens and kitchens as classrooms for hands-on education, teaching agriculture, nutrition and science to people of all ages. Participants learn how to grow food on large or small scales and to cook using nutritious, locally grown ingredients. Together, passionate community members are creating a shift in our culture and have the potential for great influence and change.

Live in Seattle or King County?

Tilth Alliance offers many fun and rewarding opportunities for you locals to get involved! Take a class, volunteer at our gardens and farms, or celebrate food and farming at one of our community events.
