Lawn Care in Georgia— Climate and Grass Overview
Georgia's lawn care market spans two distinct grass worlds divided roughly by I-20. South of Atlanta, warm-season grasses - Bermuda, Zoysia, Centipede, and St. Augustine along the coast - dominate. North of Atlanta and into the Blue Ridge Mountains, Tall Fescue becomes the primary turf as winters grow cold enough to kill warm-season grasses or keep them dormant too long to be practical. Bermuda is Georgia's most-installed sod and performs excellently in the state's hot, humid summers with adequate irrigation.
Georgia's defining lawn challenge is its red clay Piedmont soil. The dense, sticky clay that characterizes Atlanta and most of central Georgia compacts easily under foot traffic and mowing equipment, restricts drainage, and stresses turf roots in summer drought. Annual core aeration is not optional in Georgia - it is essential maintenance for any lawn on Piedmont clay.
Spring Lawn Care in Georgia
Spring pre-emergent application is the single most important task for Georgia lawns. Apply when soil temperatures reach 55 degrees at the 2-inch depth - in Savannah and the coastal plain this is late February to early March; in Atlanta it is typically mid-March; in the North Georgia mountains it may be as late as early April. The dogwood bloom (Cornus florida) is the traditional Georgia indicator for crabgrass pre-emergent timing. A second pre-emergent application 6 to 8 weeks later extends the control window through late summer germination periods.
Bermuda and Centipede lawns should not be fertilized until fully green and actively growing - typically late April in Atlanta, March in Savannah. Scalping Bermuda in early spring (late February in South GA, mid-March in Atlanta) removes dormant top growth and significantly accelerates green-up. North Georgia Tall Fescue lawns benefit from a spring fertilizer and overseeding of thin areas in March before temperatures become too warm for germination.
Summer Lawn Care in Georgia
Georgia summers are hot, humid, and unforgiving to improperly maintained lawns. Mow Bermuda at 1.5 to 2 inches and Zoysia at 1.5 to 2 inches during peak summer. Centipede, often called the lazy man's grass, thrives at 1.5 to 2 inches with minimal fertilizer - over-fertilizing Centipede is one of the most common Georgia lawn mistakes and leads to thatch buildup and winter kill. Water deeply and infrequently: 1 inch per week total, preferably in one or two sessions.
Large patch (Rhizoctonia solani) is the most destructive disease in Georgia warm-season lawns, causing expanding circles of dead turf in spring and fall when soil temperatures are 50 to 75 degrees. It is often confused with a pest problem. The circular pattern and tan, sunken appearance of affected turf at the edge of green grass are diagnostic. Preventive fungicide (azoxystrobin) applied in September and October is far more effective than curative treatment.
Fall Lawn Care in Georgia
Fall is the most critical maintenance season for North Georgia Tall Fescue homeowners. The ideal Georgia Fescue overseeding window is mid-September through October - soil temperatures are perfect for germination (65 to 75 degrees) and fall rainfall reduces establishment irrigation demands. Core aerate before overseeding on Atlanta clay soils to improve seed-to-soil contact and reduce compaction.
For warm-season lawns statewide, apply a winterizer fertilizer (high potassium, low nitrogen) in September through October to improve cold hardiness before dormancy. This application is especially important in North Georgia's Zone 7 areas where Bermuda and Zoysia experience true cold hardiness stress. Apply fall pre-emergent in September to block henbit, annual bluegrass, and chickweed from invading as warm-season grasses go dormant.
Winter Lawn Care in Georgia
Georgia warm-season lawns go dormant from roughly late November through mid-March, turning tan or light brown. This dormancy is normal and healthy. In North Georgia's Zone 6b through 7a areas, Centipede is vulnerable to winter kill in harsh winters - the grass is only cold-hardy to about 5 degrees. Avoid nitrogen fertilizer after October to prevent tender growth going into cold snaps.
Winter is Georgia's best window for soil testing. Georgia's red clay soils are typically acidic (pH 5.5 to 6.0) and many lawns benefit from lime application to raise pH toward the 6.0 to 6.5 ideal for most grasses. Apply lime in winter so it has time to work into the soil profile before spring green-up.
Most Common Lawn Problems in Georgia
Large Patch (Rhizoctonia)
Large patch is the primary fungal disease of Georgia warm-season lawns, most severe in Zoysia and St. Augustine in spring and fall. Circular patches 1 to 20 feet in diameter expand outward, with active orange-tan turf at the outer ring. The disease goes dormant in summer heat and resurfaces in fall. Preventive fungicide (propiconazole or azoxystrobin) applied in September provides the most effective control - curative treatment after patches appear is far less effective.
Centipede Decline
Centipede decline is a complex problem affecting Georgia Centipede lawns that were over-fertilized, over-limed, or planted in poorly drained soils. The lawn looks healthy in spring but fails to recover from winter dormancy, leaving large dead areas. Causes include excessive thatch, high soil pH (above 6.5), and late-season nitrogen applications. Dethatch heavily thatched lawns in May, test soil pH (target 5.0 to 6.0 for Centipede - lower than other grasses), and avoid nitrogen after August.
Crabgrass and Goosegrass
Annual grassy weeds are the most common lawn problem in Georgia, with crabgrass germinating in spring and goosegrass germinating slightly later in warmer soils. Both thrive in thin, stressed turf and become very difficult to control once established. Pre-emergent applied at the dogwood-bloom timing in March is the primary control. A second application in June extends control against late-germinating goosegrass. Post-emergent quinclorac controls young crabgrass but is ineffective on goosegrass.
Armyworms
Fall armyworms are a recurring Georgia lawn pest that can destroy a healthy lawn in 48 to 72 hours during late summer outbreak years. Moths lay eggs in August through September and larvae feed aggressively, consuming grass blades down to the soil line. Watch for birds feeding intensively on the lawn as an early warning sign. Inspect by parting grass at the edge of damaged areas in early morning or evening when larvae are active. Treat immediately with spinosad, chlorantraniliprole, or bifenthrin.
