For those with a green thumb, growing plants may seem easy. However, when plant problems arise, determining the cause of these issues can be difficult. Developing the skills necessary to determine the cause of a plant problem takes experience and time. The steps involved in the diagnostic process first require analysis of information regarding the history of the symptomatic plant and the surrounding area. Plant symptoms and signs provide additional evidence to aid in determination of a possible cause.

Diagnosing plant problems can be challenging. A site visit can provide the information necessary for a complete and accurate diagnosis. However, once on-site, it is important to know how to proceed. The following guidelines are intended to assist in the process of gathering pertinent information and determining a possible cause. Often abiotic conditions such as environment, mechanical damage, or living organisms like insects or wildlife may be to blame. Should the field site diagnosis be inconclusive and samples need to be submitted to the UK Plant Diagnostic Laboratories, the information gathered here can provide valuable supplementary information.

Volutella blight (also called Pseudonectria canker) is the most common disease of boxwood in Kentucky landscapes and nurseries. This disease is caused by an opportunistic fungal pathogen that attacks leaves and stems of damaged or stressed plants. Winter injury, poor vigor, and stem wounds increase risk for Volutella blight. All species and cultivars of boxwood are susceptible.
