This study delineates two Taiwanese TESOL teachers' efforts of combining English writing with entrepreneurship education to cultivate English majors' interdisciplinary competence in academic writing classes. An integrated business-and-writing approach was proposed to foster English majors' academic writing skills and entrepreneurial capacities. In this study, farming metaphors ("The two farmers," "Planting the seed," "Growing the seed," and "Harvest") will be used to portray the instructors' shared journey of guiding students to complete a creative business planning project. Feedback from students reveals that students gained content knowledge about the business world, and they learned how to write a business plan. For the two instructors, their endeavors to transform English writing courses to link academic knowledge with real-world purposes have encouraged them for more cross-campus collaborations to inject new energy into higher education institutions. To conclude the paper, pedagogical recommendations are provided to foster English majors' learning of English beyond disciplinary boundaries.
