Is the farm open at all during the week? What if I really need fresh sweet corn? Posted byuser April 25, 2019March 26, 2020 Leave a comment on Is the farm open at all during the week? What if I really need fresh sweet corn? During Spring & Summer, the Corner Market is open only on Fridays, Saturdays and Sundays. The farm is completely closed Monday-Thursday, so we do not have produce or anything else available for sale on those days. Needing fresh produce on a weekday? Check out local farmers markets! Oak Marr (Wednesday Mornings) Leesburg (Wednesday Afternoons) Herndon (Thursday Mornings) During the Christmas season, the Corner Market is open daily.
