Landscape Zombies

Tree and Shrub Myths that will not die Part 2

This is a two-part series titled “Landscape Zombies! Tree and shrub myths that will not die”. We all want the latest plant and soil scientific information to pass on to our clients or practice in our municipalities but how do you tell what’s science and what’s pseudoscience? Landscape professionals, in particular, can quickly lose their credibility (and business) when they end up promoting products and practices that aren’t based on reputable science. This two-part series will focus on landscape tree care and provide us with some guidelines for evaluating articles, books, and electronic resources objectively. For each myth busted, Dr. Chalker-Scott will discuss alternatives that are both practical and scientifically grounded.
