Landscape Site Assessment

9/6/2017 (new)
Authors: Ellen Crocker, Rick Durham, Bill Fountain

The most common reason trees and shrubs fail to perform as anticipated is that their cultural requirements differ from the site characteristics. People often plant things they know and love from a distant state, purchase because they are on sale, or find attractive but don't understand the environmental requirements. In some cases, a site can be easily modified to make it more suitable for a desired species. Most of the time, it is difficult or impossible to change the site characteristics enough for the plant to thrive. Appropriate watering is essential for establishment of recently transplanted trees and shrubs. This becomes even more important (and challenging) for plants poorly matched to their sites. Selecting plant species that will thrive under particular site conditions is an easier and less expensive option. The first step in doing this is to understand the site where you plan to plant.

Volutella Blight of Boxwood

Authors: Adam Leonberger, Nicole Ward Gauthier

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.

PPFS-OR-H-1

Managing Diseases of Herbaceous Ornamentals

5/1/2017 (new)
Authors: Jay Hettmansperger, Nicole Ward Gauthier

Herbaceous landscape ornamentals can succumb to various adverse factors, including infectious and non-infectious diseases. Infectious diseases are caused by microorganisms, such as fungi, fungus-like water molds, bacteria, nematodes, viruses, and phytoplasmas. Abiotic or non-infectious diseases may be attributed to unfavorable growing conditions, which can include nutritional deficiencies, improper soil pH, extreme temperatures, excessive soil moisture, or drought. In order to determine the proper course of action for treatment, it is essential to accurately identify the specific cause(s).

What's Wrong with My Taxus?

6/5/2013 (major revision)
Authors: Rick Durham, Cheryl Kaiser, Lee Townsend, Nicole Ward Gauthier

Taxus (yew) is an evergreen shrub commonly found in Kentucky landscapes. Numerous conditions can cause these shrubs to exhibit yellowing and browning symptoms. While diseases and insect pests can result in damage, Taxus troubles are often the result of adverse growing conditions. Pinpointing the specific cause requires a thorough examination of the affected shrub, an investigation of the surrounding area, and knowledge of possible stress factors.
