The spotted lanternfly (Lycorma delicatula) (SLF) is the latest non-native species to take hold in the U.S. This planthopper is large (about a half-inch long) and originally from several countries in the Far East. It was first found in Pennsylvania in 2014, and active infestations are now established in Connecticut, Delaware, Indiana, Maryland, Massachusetts, New Jersey, New York, Ohio, West Virginia, Virginia, and as of just last week, North Carolina. SLF has not been detected in South Carolina, but it is an insect for which we need to be on the lookout.
The insect has one generation per year, overwintering as eggs, which hatch in the spring. Nymphs feed and go through several developmental stages, developing the red color just before becoming adults. Adults are present starting in mid-summer and spend the rest of the summer feeding; they mate and lay eggs in the fall. In North Carolina, adults and nymphs are present right now!
SLF has over 100 confirmed hosts, and they seem to prefer feeding on fruit trees (e.g., apple, plum, peach, cherry), grape vines, and other smooth-barked tree species (e.g., walnut, birch, maple). And, in an interesting case of invasive species feeding on an invasive species, they also prefer tree-of-heaven. SLF will even feed on some vegetable plants and shrubs. Conifers do not appear to be host plants. SLF feeds by inserting its mouthparts into the host and extracting the liquids. Unused (waste) liquid is eliminated by the insect from its posterior end. This waste liquid is high in sugar and is called honeydew. Honeydew coats whatever is below the feeding insect, leaving the surface sticky. Black mold (called sooty mold) then grows on the honeydew, often attracting bees & wasps.

North Carolina State Extension wrote an excellent publication on terrestrial flatworms, with common species around yards and gardens in the Carolinas called land planarians or hammerhead worms: https://content.ces.ncsu.edu/terrestrial-flatwormshammerhead-worms.
As the year passes, and as each new season settles upon us, we are blessed with abundant and various seasonal crops and produce. While in most mainstream grocery stores, we can now find our favorite foods all year round; however, many prefer to eat what is being grown specifically in that season. Here in South Carolina, entities such as Certified SC Grown is just one example of an organization that is working to bridge the gap between field and plate, making finding local, seasonal fruits and vegetables more attainable.
No other plant native to South Carolina has such fragrant and beautiful spring blooms and stunning fall color as the witch-alders. Fothergilla was named after Dr. John Fothergill, an English physician and gardener who funded the travels of John Bartram through the Carolinas in the 1700’s. These beautiful shrubs have been planted in both American and English gardens for over 200 years, including gardens of George Washington and Thomas Jefferson.
Florida pusley is a low-branching, annual summer weed. Its pretty, white, star-shaped flowers produce an abundance of seeds, and a single plant can quickly turn into an infestation. This weed is extremely drought tolerant and can easily out compete lawns that are not irrigated during extended dry weather conditions.
The Upstate is one of the few places in South Carolina with the right climate and soil conditions to grow productive apples trees. While the actual trees can be grown in most any part of the state, higher temperatures and humidity in the midlands and coastal plains make disease pressure hard to manage.
Want to add a tropical flair to your garden this spring? Elephant ears will add a bold statement to a filtered sun or high shade spot. These striking “drama queens” of the garden may be either in genera Colocasia or Alocasia. The easiest way to tell these beauties apart is that colocasias (Colocasia esculenta) will have leaves that point downward, and alocasia (Alocasia species) leaves will point upward. Depending on the species or cultivar of each genus, the size can range from 3 to 10 feet tall and 2 to 10 feet in width. Both types of elephant ears are native to the tropical regions of Southeastern Asia.
Our South Carolina water resources help producers grow the crops we eat, supply drinking water when we turn on the tap, and support industry and our outdoor lifestyle. It is important to recognize how we use water in our community so that we can each do our part to help conserve this important resource. Do you know who is the biggest user of water in South Carolina? It may not be who you think.
The Asian longhorned beetle (ALB; Anoplophora glabripennis) is not easy to miss – adults of this large, black beetle with white spots, black and white striped antennae, and blueish feet are between 1 and 1 ½” long (Fig. 1). ALB larvae are equally striking as the large, white segmented larvae can be nearly 2” in length (Fig. 2). Established populations in the U.S. are found in Massachusetts, New York, and Ohio, and a new infestation was recently found in Charleston County, South Carolina.
Clemson University’s Cooperative Extension Service is proud to offer a brand new program to the citizens of South Carolina! Many landscape professionals, whether in the private industry, grounds-maintenance, or employed by government agencies, are in constant need of good training resources for themselves and their employees. Many homeowners also want to know that their landscape operators/providers have the skill set necessary to deliver consistent, high-quality service.
Copperhead snakes (Agkistrodon contortrix) are found throughout South Carolina and are one of the six venomous snake species, out of 38 total snake species, that our state has.
Springtime color in the residential landscape is never lacking with the multitude of flowers of many species of annuals, perennials, and shrubs. However, autumn colors may be a bit more lacking in the average home garden. This is why I have included deciduous viburnums in our landscape design. Not only do many species have outstanding fall color, but most have beautiful clusters of red, blue, pink, or glossy black fruit. Additionally, for the native plant enthusiasts, there are many species of native deciduous viburnums from which to choose. Of approximately 18 deciduous species that grow well in South Carolina, six are natives.
Rob Last reports, “Strawberry crops are developing well; however, we are seeing gray mold phomopsis blight in some crops. Sanitation can really help prevent botrytis from spreading as we move forward when allied to fungicide applications. Keep scouting for spider mites as there are active populations in some crops. Now is a great time of year to think about the maintenance of equipment for bed formation, cultivation for spring crops, and most important product application.”
