The forests of South Carolina – like those throughout the United States – certainly have their share of pests. While most of these pests are native and typically only impact stressed or injured trees, several non-native species are present and established in South Carolina. And of those non-native species, a few are true invasives, capable […]

Take just a short drive down the road or interstate, and I bet you will have a good chance of seeing Tree-of-Heaven. In the last few years, I have really started to notice this tree along the sides of roads. I have also made numerous landowner visits where I have seen it on their property. […]

Large, showy, purple wisteria flowers are covering trees along roadsides this time of year. While they are pretty, most of what you are seeing is also invasive. Several wisteria species live in South Carolina. American (Wisteria frutescens) and Kentucky wisteria (W. macrostachya) are native species. They are not all that aggressive in terms of their […]

Using Hack-and-Squirt Method to Control Undesirable Vegetation

Hack-and-squirt, sometimes referred to as frill-and-spray, is a herbicide application method that applies the herbicide into the stem (trunk) and is used to target specific undesirable trees. There is a slight variance between hack-and-squirt and frill-and-spray. Generally, hack-and-squirt refers to a cut or series of cuts around the trunk of the tree determined by tree […]

It is time to get privet under control with a method that works in the late fall that most people can do! Glyphosate is a non-restricted-use product that can be found at local places and at an affordable price. It is a non-selective herbicide product, thus why we want to use this method in the […]

There are currently 20 species of armadillo in existence, but the Nine-banded Armadillo (Dasypus novemcinctus) is the only species […]
