Prostrate spurge (Chameasyce maculatais) a low-growing, mat-forming, annual summer weed. It grows from a taproot that can grow to a depth of 18 inches and can spread as much as three feet across. It has milky, white sap, and the stems can be smooth or hairy. The leaves have a toothed margin; some can contain a reddish spot, earning it the pseudonym spotted spurge.
Spurge thrives in full sun, open, disturbed areas and can indicate that the soil is compacted. Compacted soil is problematic for turfgrasses. It diminishes the potential growth of the root system and can cause thin or bare spots to develop in the lawn. If you have a lot of spurge weeds in your lawn, consider aerating the lawn. For more information, please see HGIC 1200, Aerating Lawns.
Hand pulling is effective when plants are small but offers minimal control once plants mature because of the deep taproot. There are several pre-emergent and post-emergent herbicides that provide effective control of spurge plants. Herbicides recommendations vary by site conditions, so please contact HGIC or your local agent for a recommendation.
A single spurge plant can produce over 1,000 seeds. The seeds germinate once the soil temperature warms above 75 °F. However, the seeds need light to germinate, so the best defense against spurge is to keep a 3-inch layer of medium to coarse mulch in beds and keep your grass cut at the upper limit of its recommended mowing height. Please see HGIC 1205 Mowing Heights for more information.
A landscape dominated by spotted spurge could be suffering from a nematode infestation. Nematodes are microscopic worms that attack the root system of plants. They are very prolific in the Sandhills and Coastal Plain of South Carolina. Nematodes cause

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.
Nothing says Christmas more than a poinsettia (Euphorbia pulcherrima). Did you know that December 12th is known as National Poinsettia Day? Plant breeders have developed a wide range of colors in hues of white, purple, orange, and pink, but red poinsettias continue to be the most traditional color of the holiday season.
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.
COVID-19 has taken the world by surprise, and many people around the world have had to slow or shut things down in recent times. While many folks are working from home, one group of people who cannot are our farmers. Our farmers here in South Carolina have been working and are continuing to work each day so that the world’s food supply and our food supply here in South Carolina remains constant.
In a year when many of our favorite sporting events have been postponed or even canceled, the garden marches on! As gardeners, we have our own backyard competitions each year, keeping mental notes on which varieties we will plant again or replace due to their performance on our ‘home court’. But choosing which varieties will be in our starting lineup each year can become a daunting task.
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.
It never fails that come March and April, the desire for many of our lawns to begin to breaking dormancy is met with the horror that the only things that seem to be green are the weeds that we have been ignoring throughout winter. This may include white clover, dandelions, chickweed, the painful lawn burweed, or so any other species. These weeds may be welcome to some homeowners as some serve as early pollen sources for pollinators, but they can also be a nuisance to others.
Smilax vines go by the common names greenbrier or catbrier due to the thorns covering their stems. There are 300 to 350 smilax species worldwide. Approximately twenty-four species are native to North America, with fifteen species growing in South Carolina. Smilax grows well in moist shade and is an important food source and habitat for wildlife, including birds, rabbits, and deer.
The spring migration of ruby-throated hummingbirds from their tropical winter homes to South Carolina gardens is a highly anticipated event. These jeweled visitors usually arrive in mid-March; therefore, it is important to put up hummingbird feeders by around March 15. Nothing is more exciting than spotting the first arrivals.
After 17 long years, billions of cicadas are ready to emerge from the ground, and we’re going to hear about it! Cicadas are harmless insects with big, bulging eyes and see-through wings held like a roof over their large bodies. Some cicadas appear every year, some every few years, and some, like the “Brood X” cicadas, are about to emerge throughout the mid-Atlantic, appear periodically every 17 years.
