Science Behind the Garden Practice

For generations, gardeners pass down their successful practices. Some of these practices often appear to border on superstition, yet they’re passed from one generation to the next because they actually work. Bob Rafka, an Extension Master Gardener will discuss a number of time-honored gardening practices then attempt to explain the chemistry that makes them succeed.

Workshop is free with paid admission into the Botanical Center.*
