The Massachusetts Horticultural Society’s third annual school garden conference at Elm Bank, 900 Washington Street in Wellesley, on Thursday, February 23 will feature workshops that explore regional best practices for planning and running a garden that will not only meet educational goals, but also provide opportunities for a diverse student body, and make connections within the school community and beyond. A variety of workshops will support interested parents and volunteers, teachers, and administrators – those who have established gardens and those just breaking ground.  The event will run from 9 – 4 (blizzard day February 24), and the cost includes morning coffee and lunch.  $45 for Mass Hort members, $60 for nonmembers.  Register at www.masshort.org.
