WGST Advises Homeowners to Inspect Their Trees

Following Sunday night's strong winds across Atlanta , radio station WGST interviewed Susan Granberry of the Georgia Forestry Commission. The main question posed to Susan was: "what should people do if they are worried about their trees?"

Susan's answer? Simple. "Homeowners should immediately inspect their trees following a storm."

Excellent idea! We like that. In fact, we recommend regular tree inspections so that a property owner is prepared before any storms. If you have vary large trees, you should have them professionally inspected at least every 3 years. If you have never had your trees inspected, nowis the time. A basic inspection costs less than the yearly maintenance inspections of your furnace - and a furnace is not likely to damage anything if it falls during a storm.

Tree Removal - Atlanta procedures

Prior to making the decision to remove a tree, it is critical to determine whether the tree presents any kind of risk to your home or property. These steps are recommended to assure you are spending your money wisely and not wasting a valuable natural resource:

  1. Have your entire property inspected by an unbiased arborist. You should pay to have this service completed. A consulting arborist is going to be concerned with assessing risk, and not selling you tree removal services. It is worth every penny.
  2. Evaluate the impact the tree removal will have on your property. How will it change your landscape? Will it increase sunlight, open views, or create erosion problems? Will you need to spend additional resources in cleanup, landscaping, or replanting?
  3. Investigate the local laws concerning tree removal. The Atlanta area has many municipal ordinances that regulate tree removal on private property. Contact your local office of Community Development or City Manager. Don't forget to refer to your community and HOA by-laws as well. Many golf-course communities also have covenants affecting the removal of trees and vegetation.
Onebark Consulting Arborist provides several affordable consulting packages for homeowners and community managers.

Will trees, limbs, and branches break from the snow?

The risk is high when heavy, wet snow accumulates on the tree, the snow has a snow-water equivalent ratio of between 6:1 and 12:1, and weighs in excess of 10 pounds per square foot. This risk is greater when the trees have full leaves or are not adapted to snow. Light powdery stuff is much less likely to cause problems.

Atlanta receives Municipal Arborist Accreditation

From the Georgia Urban Forest Council - The City of Atlanta is the latest community to join a prestigious group of municipalities to be accredited by the Society of Municipal Arborists. SMA Accreditation is the highest national honor for municipal urban forestry programs.

SMA Accredited programs have a certified municipal specialist on staff, have an approved Local Forest Master Plan, are Tree City USA growth award recipients, show private contract preference for accredited tree care companies, adhere to industry standards for safety and performance, and adhere to SMA’s Code of Ethics. “The SMA accreditation is yet another example of the City of Atlanta’s commitment to excellence,” said Mayor Kasim Reed. “I commend the members of the city’s Arborist Division and the Office of Parks for their dedication and willingness to sharpen their skills and achieve the highest professional standards for the benefit of the citizens of Atlanta.”

The City of Atlanta is the first municipality to be accredited in the state of Georgia, and fifth nationwide, joining the cities of Aspen, Colorado; Glencoe, Illinois; Arlington, Texas; and Downers Grove, Illinois.

Freak Windstorm Batters Trees Across Atlanta

This morning, the metro residents were awakened to several hours of falling trees and limbs.

Although the weather system did not look particularly ominous, I struck out for my morning appointments. In northwest Atlanta, I was greeted by residential streets blocked by both dead and live trees that had toppled across the roadways. In one instance, as I backed away from a fallen tree in the Margaret Mitchell neighborhood, I caught a glimpse of a pine falling across the street behind me. I was now actually blocked on both sides!

I was able to get out of my Jeep, and quickly pull back enough of the tree top to create an escape route. This is one of the few times in storm history that I was afraid to be in my vehicle. I drove down the street to a cul-de-sac, where no tall trees existed, until the winds died down.

This windstorm was caused by intermittent downdrafts, creating wave-like patterns across the landscape. These waves are very forceful and can cause trees to fail in unexpected ways.

Eastern Tent Caterpillars Active

The eastern tent caterpillar was seen in full force yesterday. Mostly a pest of Black cherry Prunus serrata here in the Southeast, it can sometimes be seen in several other common trees as well. The caterpillar forms a dense, white 'tent' in the crotches of tree branches, where the caterpillar rests.

While it is not a particularly damaging insect, it can weaken already stressed trees by causing the host tree to sprout new leaves. This resprouting leaves the tree with a short energy deficeit in the early spring.

It is rarely worth trying to control this insect unless they are active in a high-value tree. Broadcast sprays of insecticides work well but are environmentally risky; professional systemic control with Acephate is confined and effective.

Cobb County Tree Planting Continues

Keep Cobb Beautiful’s program "Cobb Trees" is hosting its season finale tree planting on Saturday, March 21, at the walking trails of Al Bishop Park, 1082 Al Bishop Drive, Marietta.

This comes on the heels of Marietta's recent mass, citywide tree replacement program.

Volunteers are needed to help preserve and beautify this area. Check-in and refreshments begin at 8:30 a.m. with a demonstration and planting at 9 a.m. To celebrate the successful season, a cookout will follow the tree planting.

Pre-registration is required to ensure adequate food, supplies and planting materials for volunteers. To volunteer, visit Keep Cobb Beautiful, or call (770) 528-1135 and ask for the Cobb Trees program.

Ambrosia Beetle Activity Sighted in Georgia Nursery


The dreaded Asian Ambrosia Beetle has made its seasonal appearance. Asian ambrosia beetle damage was found at two Georgia nurseries [names withheld], attacking an October Glory red maple and some other woody plant material.

The Asian Ambrosia beetle is a minute ambrosia beetle of Asian origin that was first detected in the continental United States near Charleston, South Carolina. It apparently has spread along the lower Piedmont region and coastal plain to North Carolina, Louisiana, Florida, and East Texas.

Xylosandrus crassiusculus adult beetles and larva bore into the trunks of trees, excavating a system of tunnels and introduce a fungus on which they feed. The fungus clogs the xylem, killing the plant. Beetle damage can be seen as spines of boring dust, with the appearance of a broken toothpick, protruding from tiny holes. Unlike other ambrosia beetles, which normally attack only stressed or damaged plants, Asian ambrosia beetles can attack reasonably healthy plants.

Preventative insecticidal sprays can reduce infestations.
