Citrus plants are very versatile around the home and may be used as individual specimens, hedges or container plants. Their natural beauty and ripe fruits make them attractive additions to the South Georgia home scene. Cold-hardy varieties that receive recommended care may grow successfully in the coastal and extreme southern areas of the state (and to a lesser degree in more northern locations).

Chainsaw Chains and Bars
The action end of a chainsaw, or the part that cuts, is made of the bar and the chain. Chainsaw chains come in many sizes and configurations and not all saws can handle all bars. To make the right choices for the job, a saw operator should be aware of the cutter type, pitch, gauge, and cutter configuration when purchasing a chain or a chainsaw.

This publication focuses on native trees, shrubs and woody vines for Georgia. It is not our intent to describe all native species — just those available in the nursery trade and those that the authors feel have potential for nursery production and landscape use. Rare or endangered species are not described. Information on each plant is provided according to the following categories: Common Name(s)/Botanical Name/Family, Characteristics, Landscape Uses, Size, Zones and Habitat.

Is My Tree Dying?
This publication outlines a tree inspection process that will help the homeowner identity potential problems and more effectively discuss the tree’s condition with an Extension agent or certified arborist. The inspection begins at the base of the tree and moves to the canopy, highlighting potential tree health problems.

As pecan trees grow in an orchard, their tree canopies encroach upon one another, causing excessive shading, which can increase alternate bearing intensity and reduce tree health and orchard profitability. The southeastern U.S. is a relatively low-light environment, exhibiting significant cloud cover and atmospheric water vapor throughout the growing season, which can further limit sunlight in orchard systems. Mechanical hedge pruning offers a solution to this problem, which can also help minimize issues related to pecan scab, hurricanes/tropical storms, and alternate bearing.

Gloomy scale is a serious insect pest that affects maple trees in urban Georgia, but it can go undetected for years. Affected trees can show branch dieback and canopy thinning after 6–10 years, when the population reaches extremely high densities. A waxy shield covering protects females from predators and insecticide exposure, and usually gives them a convex shape.

Oak lecanium, Parthenolecanium quercifex (Hemiptera: Coccidae), is a common soft scale insect pest of oak trees and other woody plants. They infest trees under high stress, such as those planted in parking lots, greenscapes, and other urban areas. Like other soft scale insects, oak lecanium scales feed on tree sap, and they excrete the excess sugars as honeydew. Sooty mold fungus grows on honeydew, and its black color blocks sunlight and interrupts photosynthesis. Although lecanium scales have little immediate impact on twigs and branches, extensive infestation and subsequent feeding damage may weaken or kill the tree over time. The problems with lecanium scale are worsened in urban landscapes where local temperatures are generally higher. Higher temperatures decrease the relative number of parasites that feed on scale insects, and the high densities of surviving females continue to produce viable eggs.
