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.

Scale insects are very common pests of landscape trees and shrubs, yet they often are overlooked when scouting. They can, however, be responsible for chlorosis (loss of green coloration of plants due to lack of chlorophyll), branch dieback, or death of the plant. Wax scales are part of the soft scale group as they produce soft, cottony, powdery, or waxy covers that cannot be separated from the scale body. Indian wax scale and Florida wax scale are the common wax scale species that occur in Georgia. Indian wax scale is prevalent in the eastern U.S. from Florida to Maryland. Florida wax scale is found from Florida to New York and westward to New Mexico.

We can positively affect pollinator populations in our region by providing plants that help sustain them. Pollinators face the increasing challenges of habitat loss, parasite and disease pressure, and the unintended consequences of pesticide misuse. Bee forage plants can bloom season-long with careful plant selection appropriate to the region. A combination of herbaceous perennial and annual plants, trees, and shrubs can provide valuable resources to bees and other pollinators. Even grasses can be used by bees as a pollen source, while crape myrtles can provide a later season resource for pollinators. Anyone—from individual home gardeners to commercial and agricultural property managers—can promote pollinator health by selecting and planting appropriate plants. This guide provides options for selecting flowering woody plants that are attractive to bees and butterflies and sometimes have additional wildlife benefits.

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.
