The garden at Tilly Foster Farm has expanded over the years and now produces enough of a harvest that it can serve the public.  This is the first time the Putnam County-owned farm has begun selling its vegetables and herbs through a farm stand.  The garden at Tilly Foster was started four years ago and has contracts to sell its produce to Tilly’s Table for use in the restaurant and to the Office for Senior Resources, for its senior citizens’ lunch program.  County Executive MaryEllen Odell says every Tuesday through Sunday from 10am to 7pm, on the honor system, cash payments can be made.  When Tilly’s farm stand first opened last Tuesday it offered 14 varieties of vegetables. Everything is sold on a first-come, first-served basis.
