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.

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.

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 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.

Bermudagrass in Georgia
Bermudagrass (Cynodon spp.) is an important warm-season, perennial, sod-forming forage grass in Georgia and throughout the Southeast. Bermudagrass is productive from spring until fall and is well-suited for grazing or hay production. Several varieties of bermudagrass are used in Georgia, ranging from common bermudagrass to the high-yielding, good quality hybrid bermudagrasses. The best variety to use depends on your location in the state and the intended use.

Johnsongrass (Sorghum halepense) is a warm-season perennial weed in pastures and roadsides throughout central and northern Georgia. Populations may germinate from seed in spring after overwintering in the soil. However, Johnsongrass primarily emerges from dormant rhizomes in areas with a history of infestations. Rhizomes are belowground stems that produce daughter plants and storage reserves for new growth in spring. The persistence of Johnsongrass is primarily associated with extensive rhizomatous growth that enable populations to spread laterally and dominate areas by preventing desirable species from flourishing.
