Laurel wilt is a newly discovered fungal disease that presents a major threat to sassafras in Kentucky. The disease was first detected in the U.S. in 2003 and in southwestern Kentucky in 2019. Currently, laurel wilt is known to occur in eleven southeastern states bordered by Kentucky (north), North Carolina (east), Florida (south), and Texas (west). Research is ongoing to determine the impact and distribution of both the laurel wilt fungus and the redbay ambrosia beetle that carries it.

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.
Occasionally, through no fault of your own, your valuable trees and landscape plants may be damaged. Landscape appraisers are called on to assess individual plants and entire landscapes as a result of storms, human damage, destruction, and failure. Appraisals are an estimate of the nature, quality, value, or utility of an interest or an aspect of real estate.
Unfortunately the emerald ash borer is only the latest in a series of invasive pests that have recently decimated our trees. Here, we provide basic information on the death of our ash trees and what types of species are less likely to be impacted by invasive insects and diseases in the future.
Eighty to 90 percent of disease and insect problems on landscape plants can be traced back to soil problems. Plants must be adapted to the site if they are to meet our expectations of growing, remain healthy, and attractive.
Mushrooms are strange and wonderful things--some are beautiful, some are ugly, some are delicious, and some are deadly. Mushroom hunting is a fun and rewarding hobby that can turn a hike through local woods into a puzzle-solving adventure. Many people are drawn to mushroom hunting and the potential to forage for food. Unfortunately, there is a dark side to mushroom foraging: poisoning. Each year, wild mushrooms lead to numerous illnesses and even a few deaths.
