Optimizing Bermudagrass Athletic Field Winter Survival in the Transition Zone
5/31/2017 (new)

Bermudagrass is an excellent choice for use on athletic fields throughout the transition zone (which includes Virginia, Kentucky, southern Indiana, and Missouri) because of its tolerance to close cutting heights, summer vigor, positive traction characteristics for athletes, resistance to divoting and ability to withstand and recover from significant traffic during active growth. The major limitation to successful bermudagrass persistence in transition zone locations is a general lack of cold tolerance and susceptibility to winterkill. | AGR-228

Chemical Control of Turfgrass Diseases, 2017
4/4/2017 (major revision)

Turgrasses under intensive management are often subject to outbreaks of infectious diseases. Good turf management practices often greatly reduce the impact of disease by promoting healthy plants that are better able to resist infections. Even under good management, however, diseases sometimes cause excessive damage to highly managed turfgrasses. The proper use of fungicides in these instances, in conjunction with good cultural practices that promote quality turf, can be an important part of an overall disease-management program. | PPA-1

Identification and Control of Henbit and Purple Deadnettle
12/30/2016 (new)

Most of the winter annual broadleaf weeds are distinguishable from each other and thus fairly easy to key out or identify. However, there are two that show up each spring that often get people scratching their heads as to which is which---is it purple deadnettle? Or is it henbit? There are several similarities between these weeds---both are members of the mint family, both have square stems, both have sparsely hairy oval- to egg-shaped leaves, leaves of both are opposite, and both have small purple flowers that appear in the axils of the upper leaves during the spring. | AGR-226

Lawn Establishment in Kentucky
7/27/2016 (major revision)

The methods you use, the grass you select and the time of year that you plant your lawn will often determine the quality and ease of maintenance. When it comes to establishing a new lawn, the key is to do everything properly from the start so you will not have to try to fix the lawn once it is established. | AGR-50

A No-math Method of Calibrating Backpack Sprayers and Lawn Care Spray Guns
4/7/2016 (new)

Calibrating application equipment is something many people avoid because they believe it is too time consuming or that the math involved in the process is confusing. Calibration, however, is critical. Applying too much can be bad for the environment, injure the grass, and also wastes money. Applying too little can result in poor pest control and can lead to pesticide resistance. There are several methods that will calibrate sprayers but the no-math method is likely the most simple and reduces the chance of errors. | AGR-220

Turfgrasses of Kentucky
8/17/2015 (new)

Roughly 7,500 grass species are grown around the world, but only 14 species are adapted as turfgrasses that have been used extensively. Kentucky is situated in the transitional climatic zone of the United States, the middle point between the cool north and the warm south, with warm summers and cool winters. Because of its unusual climate, no single grass is suitable for all situations and locations. The majority of the turfgrasses that are appropriate for use in Kentucky are known as C3 grasses, or cool-season grasses. Cool-season grasses differ from warm-season grasses (C4) in many ways, but most notably in their photosynthetic pathways. Warm-season grasses can tolerate and even thrive during the warm summers while cool-season grasses may become heat-stressed. Conversely, winters in Kentucky may be too cool for warm-season grasses and greenup in the spring may be long and arduous. Warm-season grasses enter a dormancy period during the fall and winter and may stay in this state as long as six or seven months. | AGR-216

Herbicide Recommendations for Weed Control in Kentucky Bluegrass and Tall Fescue Lawns for Professional Applicators
3/30/2015 (new)

The best method to control weeds is to grow a dense and healthy lawn. This objective should be primary for turf professionals. Lawn weed control is facilitated by identification of the turfgrass and weed species present. Not all herbicides will control all weeds, and not all herbicides are safe on all lawn grasses. This publication contains herbicide recommendations for licensed professionals. For information on weed control for non-professionals, see AGR 208: Weed Control for Kentucky Home Lawns. | AGR-218

Brown Patch Disease in Kentucky Lawns
12/1/2014 (new)

Brown patch, also called Rhizoctonia blight, is a common infectious disease of turfgrass. All turfgrasses grown in Kentucky lawns can be affected by brown patch. However, this disease is usually destructive only in tall fescue and perennial ryegrass during warm, humid weather. While brown patch can temporarily harm a lawn's appearance, it usually does not cause permanent loss of turf except in plantings less than 1 year old. | PPFS-OR-T-12

Irrigation Tips to Conserve Water and Grow a Healthy Lawn
11/11/2014 (major revision)

The goal of water conservation in the landscape does not need to be as drastic as eliminating all irrigation, but we should choose plant material wisely and decide if and when irrigation is necessary. This publication is designed to promote a healthy lawn through watering while promoting water conservation through best management practices. One of the easiest things you can do to reduce the need for irrigation in your yard is to plant species that naturally need less water. When choosing plants, remember that just because a particular plant is drought tolerant does not mean that it is suitable for Kentucky's climate. | AGR-115

Aerifying and Dethatching Lawns
11/3/2014 (major revision)

Lawns in Kentucky will occasionally suffer due to compacted (hard) soils and excessive thatch layers. Although most lawns will not have problems with these issues, you may occasionally need to dethatch or aerify (core) to maintain a high quality lawn. | AGR-54

Improving Turf Through Renovation
11/3/2014 (major revision)

Often a poor lawn can be improved by using proper maintenance practices, including mowing, fertilizing, watering, and pest control. In some instances, however, portions of the lawn must be reseeded. Usually one of two methods is used to re-establish a lawn: conventional or renovation. The conventional method involves killing existing vegetation, tilling the soil, and replanting. The advantages of conventional tillage include more complete control of weeds and undesirable grass, a smoother soil surface, and the opportunity to improve the existing soil by adding organic matter and sand. Renovation involves replanting without completely tilling the soil and often without destroying all existing vegetation. | AGR-51

Considering the Environment in the Maintenance of Your Kentucky Lawn: A Season by Season Approach
7/30/2014 (new)

Most people do not realize the environmental benefits of lawns. Lawns are known to cool the air, reduce soil erosion, remove dust and pollutants (including CO2) from the air, reduce run-off of water and pollutants, create oxygen for humans, and improve soils over time by supplying organic matter. Lawns are also important aesthetically and have been shown to improve human well-being. However, to be 100 percent environmentally friendly, we could never fertilize or water our lawns and only mow with a self-propelled reel mower. Or, we could get rid of our lawn altogether. Neither of these options is particularly appealing for most people. We can, however, have a high quality lawn and reduce our impact on the environment by doing some very simple things at the right times of the year. The following guide will walk you through a series of steps that are important for keeping your lawn looking thick and healthy and at the same time reducing pests and the need for chemicals and other inputs. | ID-222

Liming Kentucky Lawns
7/22/2014 (new)

Most homeowners desire an aesthetically pleasing landscape and will take steps to ensure success. Proper fertilizing, watering, and pest control are all steps that will lead to a quality lawn. However, some confusion surrounds when and why lime should be applied to a lawn. Many homeowners believe that lime needs to be applied on an annual basis for a quality lawn. The purpose of this publication is to explain why lime is needed and whether it is required on your lawn. | AGR-214

Fertilizing Your Lawn
7/22/2014 (new)

Lawns require fertilizer to remain healthy. Proper fertilization practices will lead to a thick, dark green, uniform lawn that is competitive against weed and disease invasions. The nutrients contained in fertilizers are necessary to support many processes occurring within the plants. If any essential nutrient is limiting, the plants will not perform at their highest level. | AGR-212

Calibrating Fertilizer Spreaders for the Home Lawn
3/25/2014 (new)

How much fertilizer should you use on your lawn? Too much can result in turf burn, wasted product and money, and potential environmental concerns. Too little will result in a low-density lawn that will not be attractive or competitive against weed invasions. To insure that you apply the proper amount of fertilizer to your lawn, you must calibrate your fertilizer spreader. You should calibrate your spreader each time you use a new (different) fertilizer because not all fertilizers have the same particle size or density. The information on the fertilizer bag is a good starting point for the calibration process but remember that spreaders can differ significantly. Calibrating your spreader will take a little bit of work, but the series of fairly simple steps below will help you complete the task. | AGR-211

Mowing Your Kentucky Lawn
4/15/2013 (new)

Mowing is a recurring cutting of a portion of a grass shoot. Lawns are mowed to maintain topgrowth within a specific range, to control weed plants that are intolerant to mowing, or to sustain an ornamental turf. Mowing is usually thought of as the most simple of lawn maintenance practices; however, even though we perform it more than any other, it can result in mistakes. | AGR-209

Weed Control for Kentucky Home Lawns
2/25/2013 (new)

The best defense against weed problems in home lawns is a healthy and dense lawn. In thick lawns, weed seeds may not germinate because light may never reach the soil surface. A thick lawn is competitive with weeds, keeping them from growing and reproducing. Developing a healthy and dense lawn comes from using cultural practices such as proper grass species and cultivar selection, proper mowing heights and fertilization, and other good management practices. The need for herbicides to control weeds in home lawns can be greatly reduced if the lawn is well maintained. | AGR-208

Turfgrass Color: Indicator of Septic System Performance
9/13/2012 (new)

Many homeowners notice color differences in the turfgrass over their septic system soil treatment area. Most often, homeowners observe green or brown stripes in their turfgrass relative to the surrounding lawn. This discoloration is worth keeping an eye on because turfgrass color is often an early sign that serious problems are about to occur. | HENV-506

Trees, Turf, and People
8/6/2012 (new)

The shade trees and fruit trees that we treasure in our landscapes were originally adapted to growing in forests in close association with other trees. In the forest they can remain small for many years. As soon as there is an opening in the canopy allowing light to reach the forest floor they grow rapidly. This great height allows trees to assume a place of dominance over other plants; their trunks lift their leaves high into the air, allowing them to intercept the maximum amount of sunlight before it reaches other plants. Thus, trees grow tall and provide us with their much-appreciated shade. | ID-203
