    Managing Imported Fire Ants in Urban Areas

    Imported fire ants interfere with outdoor activities and harm wildlife throughout the southern U.S. Ant mounds are unsightly and may reduce land values. Although fire ants do prey on flea larvae, chinch bugs, cockroach eggs, ticks and other pests, the problems they cause usually outweigh any benefits in urban areas. While it is not possible to eradicate this species, controlling fire ants is highly desirable. The best control programs use a combination of non-chemical and chemical methods that are effective, economical and least harmful to the environment.

    2026 Green Industry Outlook

    The key points for 2026 are: 2025 was a good year for many green industry firms as there was strong demand in many parts of the state; there are many unknowns going into 2026 that will impact green industry sales: mixed signals within the economy, increased input costs, and in particular the varying strength of the housing market in Georgia will play a major role; green industry demand is expected to slow, with prices expected to decrease to offset the decreased demand, which will result in decreased sales in 2026 compared to 2025.

  • Turfgrass Fertility: Understanding Fertilizer Labels, Macronutrients, and Micronutrients

    C 1058-2

    Turfgrass Fertility: Understanding Fertilizer Labels, Macronutrients, and Micronutrients

    A regular fertilization program is important to maintain healthy, attractive turf and should include applying the correct analysis of fertilizer, using the correct amount, and fertilizing at the proper time. Turfgrasses require a number of nutrients for growth. Three of these—carbon, hydrogen, and oxygen—are rarely lacking because grasses get these elements from carbon dioxide in the atmosphere and water from the soil.

    The remaining eighteen essential elements are also obtained from the soil. Nitrogen (N), phosphorus (P), and potassium (K) are needed in the highest concentrations. These major elements are commonly supplemented with fertilizer. The three numbers on the front of fertilizer bags are often called the ”N-P-K” numbers.

    In addition to these major nutrients, secondary nutrients and micronutrients are also essential for plant growth. Understanding fertilizer terminology and the different types of nitrogen sources is important when establishing a lawn management plant. Nontraditional or “organic” fertilizers are also an option for homeowners.

    Turfgrass Fertility: Soil Texture, Organic Matter, Aeration, and pH

    Successful lawn care requires a basic understanding of soil properties. A healthy plant starts with healthy soil. Soil is a complex relationship of soil minerals, organic matter, soil inhabiting organisms, and plants along with water and air. Understanding when and how to aerate the soil and understanding what pH is and how it affects plant health is essential for turfgrass health. This publication aims to help homeowners and landscape professionals improve soil fertility through the techniques discussed.

    Grasscycling: Let the Clippings Fall Where They May

    Grasscycling is the natural recycling of grass clippings by leaving them on the lawn after mowing. Grasscycling saves time, effort and, when done properly, is good for the environment and health of the grass. This publication describes the process of grasscycling, a practical and environmentally responsible way of recycling grass clippings in the landscape.
