Hemlock Woolly Adelgids

Hemlock trees are everywhere in the north Georgia mountains and they are often used in suburban landscapes. But several years ago, tree experts began to notice that hemlocks were being killed by adelgids, small insects that are kin to a mealybug. Walter visits with forester Scott Griffin to learn more about adelgids and their control.

Walter Removes a Tree

When a big dogwood died in Walter's landscape, he needed to remove it without digging a big hole around it. He used a hand-operated winch, some heavy chain and a nearby pine tree anchor to pull the dogwood over. Gravity did most of the work! Watch him jump out of the way when the tree starts falling... only to find it was a false alarm!

Cankers

Walter hankers to talk about cankers, especially the common ones you might find in landscape trees. If you have pine trees, you’ve probably noticed the swollen branches of fusiform canker. And Walter says this fungus also causes another odd phenomenon: brooming needles, which looks like a huge squirrel nest in the top of a pine tree. Black knot and pitch canker are also put under his curious examination.
