Professors Sadof and Beckerman emphasize the importance of a holistic approach to plant care. Recognizing the significance of beneficial organisms, the Purdue Plant Doctor features a section devoted to these garden allies. By understanding the role of beneficial insects and embracing Integrated Pest Management (IPM) principles, gardeners can foster a healthy ecosystem that naturally minimizes pest and disease issues. Prevention through conscientious cultural practices is always the first line of defense.

The Path Ahead

As the gardening season progresses, certain plant issues tend to dominate gardeners’ concerns. For instance, boxwood problems, like boxwood leaf miner, commonly arise during spring, along with issues stemming from erratic weather patterns. Wet springs can lead to prolific plant growth, attracting sucking insects and foliar diseases. Subsequently, hot and dry periods can give rise to spider mite infestations and borer activity.

With experience, an increasingly discerning eye will develop, enabling gardeners to make more informed decisions.
