Most people these days have, at the very least, heard of Callery and Bradford pear trees and know something about the invasiveness of this ornamental street tree. But I still get questions about what it is and why it’s so bad. So, I’d like to offer a little history of this infamous tree. Where did[Read More…]
Asian bush honeysuckle (Lonicera spp.) is an extremely invasive plant that is a serious problem in most areas of the Midwest. These invasive plants grow very fast, especially along woodland edges, and shade out most of the understory plants that are found in these areas. Honeysuckle can also significantly reduce the available browse for deer[Read More…]

All plants can fall victim to insects, diseases, and environmental problems. How they respond to this stress is often the same: Wilting, yellowing, holes, rots, blight—it’s a long list! With so much overlap in symptoms, it can be quite a challenge for people to identify their plant health problems accurately, quickly, and inexpensively. The Purdue[Read More…]

Throughout the decades, many landscape fads have ended in failure. Dame’s rocket, wintercreeper, and purple loosestrife are a few examples of beautiful and vigorous ornamentals that have wreaked havoc on our natural ecosystems. Nursery professionals, as well as consumers, were unaware of the potential negative impacts of non-native species, often marketed as vigorous, hardy, or[Read More…]
