Most gardeners know the impressive benefits of homegrown compost, but did you know that by steeping compost in water you can produce a superior product? Join author Christopher Roddick, head arborist at the Brooklyn Botanic Garden and certified Master Composter, at the Polly Hill Arboretum on Saturday, June 11, from 9 – 1, to learn the process of making compost tea. This workshop will cover how to make high-quality compost and the logistics of producing and using compost tea. Roddick will also discuss the relationship between plants and soil and how to improve plant and soil health.  $45/$40 for PHA members. (Includes mid-morning refreshments.)  For directions and registration information, visit www.pollyhillarboretum.org.
