This six session course will begin with a segment on the identification of the most common invasive plant species encountered in woodlots, fields, gardens, and similar sites. Appropriate management and control techniques will be discussed, as will commercially available herbicides. The understanding of invasive plant species dynamics and proper control techniques gained in this course will enable gardeners and landscapers to safely, effectively, and economically keep unwanted plants to a minimum. The course will be held at Tower Hill Botanic Garden, 11 French Drive, Boylston, Massachusetts, each Wednesday evening beginning September 30 through November 4, from 6 – 9 pm, and will be taught by Mike Nelson, Norfolk County Agricultural High School.  Tuition is $400 for Tower Hill members, and $445 for non-members.  The non-member fee includes a one year individual Tower Hill Botanic Garden membership, since if you’re forking out the big bucks you should at least be a member, which will entitle you to many other great discounts and opportunities.  To register, log on to www.towerhillbg.org before September 23.
