Margaretha Haughwout hails from San Francisco where she worked with the Guerrilla Grafters art/ activist group, and Hayes Valley Farm, a 2.5 acre interim-use permaculture farm built on top of a former freeway, ruined from the Loma Prieta earthquake. For this workshop, she will introduce the wedge grafting techniques and give a brief talk based on her recent essay “The Politics of the Graft.”
