Tower Hill Botanic Garden, 11 French Drive, Boylston, Massachusetts, will host Tom Dzaugis of Green Path Garden Supply on Saturday, February 12, from 10 – 11:30, for an Introduction to Hydroponics. Grow vegetables all year long! This class will cover the basics of hydroponics, which is simply growing plants in a non-soil growing medium. This can be a very simple and effective way to grow vegetables which can yield amazing results. We will cover the different growing mediums available, why pH is important, the difference between fertilizers for soil and hydroponics, and lighting. The class will conclude with a Q&A discussion. Fee for the class is $10 for THBG members, $12 for non-members, and you may register on line at www.towerhillbg.org.
