What Is a Carbon Footprint and How Does It Relate to Landscape Plants?
6/10/2019 (new)

Carbon footprint is a term used to describe the impact of greenhouse gas emissions associated with a product or activity. The objective of this publication is enhance the reader's understanding of carbon footprint (CF) terminology and the science underlying its determination. Having such an understanding is necessary for managers and developers to minimize the negative environmental impacts of new product development and assess positive or negative cradle-to-grave life-cycle impacts. Life cycle assessment has been used to characterize the CF of representative field-grown and container-grown landscape plants. | HO-123

Calibrating Boom Sprayers for Turf Applications
3/12/2019 (new)

Calibrating application equipment is something many people avoid because they believe it is too time consuming or that the math involved is too confusing. Calibration, however, is critical. Applying too little can result in poor pest control and can lead to pesticide resistance. Whereas, over applying can be bad for the environment, damage the grass, and wastes money. There are several methods for calibrating sprayers. Choose the one that makes the most sense to you. Three different methods are described below. All these methods are reliable and will provide very similar application accuracy. | AGR-239

Establishing and Managing Bermudagrasses in the Transition Zone
11/12/2018 (new)

Bermudagrasses have been successfully grown on athletic fields and golf courses in the transition zone for many years. Although each year some level of winterkill threat exists, bermudagrass remains an excellent surface for golf and sports. Seeded varieties of bermudagrasses have been the most common choices in Kentucky due to the availability of seed of good varieties as well as the ease of planting seed versus living plant material. There are, however, several outstanding vegetative bermudagrass cultivars that are adapted to the transition zone. | AGR-238

Grass Options for Athletic Fields in the Transition Zone
3/2/2018 (new)

There are several grasses that will grow in the transition zone, but none all that well. Our summers are often too hot for cool-season grasses like Kentucky bluegrass and our winters are often too cold for warm-season grasses like bermudagrass. Keep in mind, however, that the problem with most poor athletic fields is not grass selection, but rather over use, lack of maintenance, and/or use when field is wet or cannot recover. | AGR-237

Reducing Heat Stress to Container-Grown Plants
11/14/2017 (new)

Production of plants in containers offer many advantages over field production. Shorter production cycles, larger numbers of plants per acre, and the ability to continuously market and ship plants are among those advantages. However, there are some disadvantages including more intense cultural practices, a relatively short window of optimum marketability due to container size restrictions, and rapid daily temperature fluctuations within the container substrate (growing medium). This publication will provide information about plant response to high root-zone temperatures, identify critical temperatures, describe the factors that influence temperature fluctuations, and suggest cultural practices to reduce heat stress in container-grown plants. | HO-119

Woody Cuts
8/22/2017 (minor revision)

Woody cuts are portions of woody ornamentals used for floral or decorative purposes. These include foliage, flowering branches, fruit and seeds, as well as bare stems and branches. Numerous shrubs, trees, and woody vines can be grown commercially for these purposes. Cut flower growers may want to add woody cuts to their production line to diversify their products, expand their markets, and extend the floral season. Growers will need to be familiar with the different production and harvest requirements of a diverse group of plant material. | CCD-CP-76

Garden Mums
7/13/2017 (minor revision)

The garden mum (Chrysanthemum spp.) is a popular herbaceous perennial flowering plant that is commonly grown for fall sales. While also referred to as 'hardy mums,' their actual hardiness outdoors (that is, their ability to survive the winter) can vary by cultivar, time of planting, and environmental conditions. Garden mums are generally container-grown in Kentucky, either in a greenhouse or outdoors in connection with a greenhouse business; there is also some field production in the state. | CCD-CP-71

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

Lavender
4/25/2017 (new)

Large-scale lavender production in Kentucky is limited by climatic requirements (low humidity and low winter temperatures ), poorly drained soils and the scale requirements for essential oils processing. Lavender could be suited as a specialty/niche crop for some Kentucky farms, especially those with ongoing agritourism enterprises. Marketing constraints and the scale requirements for essential oils processing make lavender more likely suited as a crop for ornamental or on-farm agritourism potential (lavender festivals) in Kentucky. | CCD-CP-127

Greenhouse-grown Specialty Cut Flowers
11/11/2016 (minor revision)

"Specialty cut flowers" generally refers to cut flower species other than roses, carnations, and chrysanthemums. Some of the specialty cut flowers that can be grown successfully in Kentucky greenhouses, or other protected environments such as high tunnels, include anemone (Anemone spp.), Asiatic or oriental lilies (Lilium spp.), bachelor button or cornflower (Centaurea spp.), celosia or cockscomb (Celosia spp.), coral bell (Heuchera hybrids), freesia (Freesia hybrids), larkspur (Delphinium spp.), lisianthus (Eustoma spp.), snapdragon (Antirrhinum spp.), pollenless sunflowers (Helianthis annus) and zinnias (Zinnia spp.), and sweetpea (Lathyrus odoratus). | CCD-CP-58

Goldenseal
4/15/2016 (minor revision)

Kentucky is a major harvester of wild goldenseal. Unfortunately, a decline in native populations has occurred as demand and harvesting pressure has increased. Like ginseng, goldenseal is listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) agreement. As such, international trade of goldenseal is closely controlled to prevent over-exploitation that could lead to further endangering the species. | CCD-CP-54

Christmas Trees
8/18/2015 (minor revision)

Christmas trees can be grown on relatively small parcels of land. This enterprise can fit in well with an existing farm or nursery operation. While Christmas tree production does have a high profitability potential, it is also a long-term, risky investment requiring periods of intensive labor. | CCD-CP-67

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

Hanging Baskets
11/26/2014 (minor revision)

Incorporating hanging baskets in with bedding plant production enables growers to generate income from otherwise unused space above benches and in walkways. Hanging baskets can fetch a higher price (on a per plant basis) than small pots and can, therefore, enhance the profitability of greenhouse bedding plant operations. In some cases, growers may devote whole greenhouses or sections of greenhouses to hanging basket production. | CCD-CP-59

Poinsettias
5/1/2014 (minor revision)

Poinsettias (Euphorbia pulcherrima) are subtropical plants which originated in Mexico and Guatemala. In their native climate, poinsettias are small woody shrubs that may reach a height of over 10 feet. In the U.S. poinsettias are grown as indoor potted plants popular at Christmas time. While the showy bracts are suggestive of flower petals, they are really modified leaves. The actual poinsettia flowers are less conspicuous by comparison, forming a yellow to red cluster in the center of the bracts. | CCD-CP-64

Ornamental Corn
4/24/2014 (minor revision)

Ornamental corn (Zea mays) production currently represents a new crop for Kentucky, in terms of limited University of Kentucky research. There are many kinds of ornamental corn, varying in ear size, kernel color, husk, and stalk color. Some cultivars have red or purple stalks and leaves that are sold for decorative purposes. | CCD-CP-72

Willows for Cuttings
7/18/2013 (minor revision)

Willows (Salix spp.), well known for their flexible and vigorous growth, have long been popular in basket and furniture making. A versatile woody plant, various species can also be used for trellises, fencing, floral arrangements, and artistic sculptures. Its fast growth makes willow a popular landscape ornamental, as well as a potential bioenergy crop. This profile will emphasize the production of willows for live cuttings and dried rods. | CCD-CP-75

Edible Flowers
9/5/2012 (minor revision)

Edible flowers can complement a cut flower or herb business, providing additional opportunities for value-added products. However, they require a specialized niche market that may take some time to develop. Flowers intended for human consumption must be grown without pesticides, providing organic growers a production edge. Plant material obtained from most commercial florists, garden centers, and nurseries is not pesticide-free and, therefore, is NOT suitable for consumption. | CCD-CP-69

Poinsettia Diseases
5/1/2010 (minor revision)

Poinsettias grown through the fall months for Christmas sales are vulnerable to destructive diseases from the time the cuttings are stuck into the rooting media until they are mature and ready for sale. A number of poinsettia diseases are favored by the same environmental conditions that promote propagation, making plant material at this stage particularly vulnerable. Diseases occurring in the later stages of production can be related to management issues or cultural problems, as well as the cooler temperatures needed for finishing. Some other diseases can be problematic to poinsettias at any phase of production. And finally, a phytoplasma organism found associated with poinsettias provides evidence that some host/pathogen relationships can actually be economically beneficial. | PPFS-GH-6
