Storm Damaged Tree Cleanup
Trees are often damaged in storms and can be extremely dangerous to clean up. Storm damaged trees are subject to all the perils associated with tree felling and much more. Working conditions may be difficult. Downed trees may be entangled in other trees, or tossed on buildings, vehicles, or wires. Energy stored in compressed limbs and trunks can be release suddenly, explosively, and fatally. Each situation is unique and requires careful consideration. Application of the included five-step cutting plan will help keep the saw operator safe and working effectively. Authors include E.M. Bauske, P. Kelley, W. Williams, and A. Martinez-Espinoza.

The fall webworm, Hyphantria cunea (Drury) (Lepidoptera: Erebidae) is a polyphagous caterpillar pest of ornamentals and trees in Georgia. “Polyphagous” means that it can feed on many types of food, and the fall webworm is known to feed on more than 600 species of plants, including row crops, herbaceous plants, shrubs, fruit, and ornamental trees in orchards, nurseries, and landscapes. Fall webworm larvae construct silk web nesting to facilitate feeding, to escape the attack of natural enemies, and for heat retention. The webbing is considered unsightly, and feeding on foliage inside the nest leads to extensive defoliation. The fall webworm can quickly reduce the aesthetic appeal of landscape trees and shrubs, and severe infestation can cause considerable damage to trees.

Excessive fertilization does not equate to greater crop yields. Crop yields are optimized when nutrients are efficiently used, which requires fertilizer applications to be based on the right source, the right time, the right rate, and the right placement. These are referred as the four Rs of fertilizer management, whose purpose is to supply plants’ nutrient requirements, reduce production costs, and mitigate environmental impact.

Muchas personas ayudan con la limpieza de los árboles después de las tormentas. Algunos son ciudadanos voluntarios; otros son trabajadores del sector público y privado que pueden o no tener experiencia con motosierras. Este PowerPoint cubre la información que todo operador de motosierra necesita saber antes de encender la motosierra. Los temas incluyen equipo de protección personal, las cinco características esenciales de seguridad de una motosierra, transporte seguro, arranque seguro de la motosierra, plagas de insectos, inspección del sitio y riesgos con electricidad/electrocución.

Many people help with tree cleanup after storms pass through. Some are citizen volunteers, and others are private and public sector workers who may or may not have experience with chainsaws. This presentation covers the information every chainsaw operator needs to know before turning on the saw. Topics include personal protective equipment, the five essential safety features of a chainsaw, safe carry, safe start, insect pests, site inspection, and electrical/electrocution hazards. Authors include E.M. Bauske, W. Williams, H. Kolich, J. Fuder, and A. Martinez-Espinoza.

There are many ways to manage grapevine growth, and many grape-growing regions implement unique and preferred training methods. Vine growth management is achieved by applying a trellising system, which is a framework of metal cross arms, wires, and support posts that are used to direct grapevine vegetation to maximize fruit quality and production. Trellising and pruning combinations will sometimes be referred to as “training” systems, but “trellising,” “training,” and “pruning” are not interchangeable terms. Understanding the different forms of trellising and pruning can be a challenge for new growers. The goal of this publication is to provide a general introduction to some of the more common trellising and pruning terms used to describe grapevine management systems. There is a glossary at the end of this publication.

There are two main trellising system categories: divided and single canopy. Jerry Watson, a grape grower and owner of Austin County Vineyards in Cat Spring, Texas, developed the divided canopy “Watson System” in 2002 to solve some issues he was having with bunch rot management and harvest inefficiency in his ‘Blanc Du Bois’ and ‘Lenoir’ vineyards. By adding a series of cross arms and catch wires to his high wire system, Jerry was able to improve spray penetration to the fruit zone and increase picking efficiency at harvest. The Watson hardware and wires separate clusters from the canopy foliage and limit cluster touching compared to a standard, single high wire system. The Watson system has since been employed in the Southeastern U.S. and can be found as far west as California. The Watson system is currently used for training hybrid and trailing grape cultivars such as, but not limited to, ‘Blanc du Bois’, ‘Norton’, ‘Lenoir’, ‘Lomanto’, ‘Crimson Cabernet’, and ‘Villard blanc’. A high wire-trained vineyard, such as those planted with ‘Chambourcin’, ‘Seyval blanc’, ‘Vidal blanc’, ‘Traminette’, and other cultivars could be retrofitted to Watson training with success. Future research will evaluate hybrid and Vitis vinifera cultivars that have yet to be evaluated for training on the Watson system.

New ornamentals have long been considered the lifeblood of the green industry. This publication contains recommendations for best-performing new annuals based on research conducted at the Trial Gardens at the University of Georgia, showcasing the plants that were awarded Classic City Awards in 2019.
