Autumn has arrived in Kentucky and, as leaves change color and fall from trees, it is time to focus on landscape sanitation. Good sanitation practices can help reduce disease-causing pathogens. These organisms can survive for months or years on dead plant material or in soil, causing infections in subsequent years. Elimination of disease-causing organisms reduces the need for chemical controls and can improve the effectiveness of disease management practices. Following these sanitation practices both in autumn and throughout the growing season can reduce disease pressure in home and commercial landscapes. Continue reading
Composting Fall Leaves
As the fall season progresses, many folks obtain large amounts of leaves and other yard wastes that need to be removed from their property.
When you compost leaves, other yard debris and kitchen waste, a microbial process converts these items into a more usable organic amendment. You can use finished compost to improve soil structure in gardens and landscape beds. You also can use finished compost as a mulch to help reduce weed problems, moderate soil temperatures and conserve soil moisture.

Brown Marmorated Stink Bugs
While monitoring vegetable and soybean fields in the Lexington area, I have noticed that the number of brown marmorated stink bug (BMSB) adults has dropped off as the numbers of nymphs on these crops has remained constant. Last year, BMSB began to gather on the sides of homes the first week in September. This makes me believe that BMSB is changing its behavior from plant feeding to begin searching for overwintering sites, possibly your home. I did spot 15 BMSB on the side of my house on Saturday. So, over the next several weeks we should expect BMSB to gather on buildings in search of suitable overwintering sites. Once inside buildings they will remain active until mid-spring.

Choosing the Right Tree Species
You have finally decided to plant a tree in the front yard. Congratulations! The big question now: Which tree?
First, there is no perfect tree. All trees have both good and bad characteristics. Most trees are more or less adaptable to your specific site. Some are more susceptible to disease and insect damage than others. The best advice is to plant a diversity of species. Choose trees for shade, some that bloom and a few just to be ornamental.

Fall Tips for the KY Garden
Fall is a beautiful time in Kentucky gardens, but it can also be a messy time. Tree leaves turn from green to vibrant fall colors and then drop, creating big piles. Then there are the leaf and spent shoots from our flower beds. The way we address our yard waste can have a significant impact on our gardens and on the environment. Gardeners commonly rake up and bag leaves to haul away to yard waste dumps. Continue reading
Control Dandelions in the Fall
Common chickweed, henbit, and purple deadnettle are cool-season weeds we usually see in crop fields during the fall and winter.
However, other weeds, such as dandelions, have become more prevalent in recent years. Dandelions are generally considered a major lawn or pasture weed but are increasingly found in grain crop fields.
