Woolly aphids are small white insects that infest hackberry trees. These insects suck the sap out of leaves and secrete a sticky substance called honeydew. A tell sign of these pest is a black sooty mold on the leaves, stems, and sometimes bark of the tree. Sooty mold will also cover anything underneath the tree.
Boutte Tree offers a systematic insecticide treatment that is poured or injected into the ground and allows the roots to take the material into the branches and leaves. This provides control throughout the entire year.
Danish start up, Allumen, is working on creating glow in the dark trees to line its city’s streets. By replacing street lights, cities will save money on energy bills and reduce emissions. This, of course, will take years of research and development before it becomes reality. What’s the downside? Genetically engineered plants could potentially harm other plants and animals; and even confuse birds.

An invasive species is one that is not native to a given ecosystem. Invasive species cause economic and environment harm, and can even be detrimental to human health. These species grow at very fast rates and can displace native species. Some examples are the autumn olive, kudzu, chinese privet, and mimosa.
Make sure a plant is not invasive before buying and planting! Soil, insects, equipment, and pine straw all contribute to the spread of invasive species. It is important to clean and inspect all equipment used at or near infested sites.
Georgia Forestry Commission advises: “Herbicides can be used to effectively control both large and small infestations. Use herbicides carefully. Many herbicides are not selective and will kill all surrounding vegetation or may harm aquatic systems. Before buying, mixing, and use of herbicides, read and follow label information and wear the appropriate safety gear. Contact your county extension agent for specific recommendations on herbicide use. Detailed information about chemical control options can be found at www.invasive.org.”
Branches – Living branches are easy to bend. If the branches snap, they are dead.
Leaf Color – The leaf color should match the season it is in.
Insects – Check for visible insects on the tree.
Bare Patches – For Evergeen trees, look for sections of the tree without leaves year round. Some causes of bare patches are: animals eating leaves, pesticide damage, nutrients and water not reaching the branches
