Savannah lawn care is shaped by humid subtropical conditions with hot summers and mild winters across most of the state. With an essentially year-round growing season each year, warm-season Bermuda, Zoysia, and Centipede (with tall fescue in North Georgia) dominate residential yards across the city. Savannah's specific micro-climate sits in USDA Zone 9a, where frost is rare and growing conditions persist nearly year-round - a window that determines almost every lawn care decision a Georgia homeowner makes during the year. Local soil conditions across the city range across red Piedmont clay or coastal sandy soil, and the dominant grass choice for any given lot depends as much on sun exposure, foot traffic, and irrigation availability as on the broader state climate.
Savannah warm-season lawns begin their year-round active growth pattern with only the briefest slowdown in the coolest weeks of January, with peak growth running from May through September and only minor slowdowns in the coolest weeks of December and January. The single most important annual maintenance task is late-spring aeration in May or early June during peak active growth, when warm-season grass recovers quickly. Pre-emergent crabgrass herbicide applied in late January through early February before soil reaches 55 degrees prevents the bulk of summer weed pressure. Lawns continue active growth through winter in this nearly frost-free climate, with only minor color loss during the coldest January nights and a quick spring recovery by February.
The biggest lawn care challenge in Savannah is red Piedmont clay soil. The dense, sticky clay that characterizes Atlanta and most of central Georgia compacts under foot traffic and mowing equipment, restricts drainage, and stresses turf roots in summer drought. Annual core aeration is essential. Large patch (Rhizoctonia) is the most destructive disease in Georgia warm-season lawns, causing expanding circles of dead turf in spring and fall when soil temperatures sit between 50 and 75 degrees.
This guide covers everything a Savannah homeowner needs to know about lawn care in 2026: the city's specific frost dates, the best grass types for Zone 9a, month-by-month mowing heights, fertilizer timing tied to local soil temperature triggers, aeration and overseeding windows that match warm-season Bermuda, Zoysia, and St. Augustine, and irrigation schedules calibrated to Georgia climate norms. Savannah's active water restrictions cap outdoor watering at 3 days per week through December 31, 2026, and the watering schedules below are built around the current restriction window. Use the seasonal cards below for spring, summer, fall, and winter task lists, the topic guides for deeper coverage of fertilization, overseeding, and aeration timing, and the FAQ section at the bottom for quick answers to the questions that Savannah homeowners ask most often. The complete annual reference is built around your specific Savannah property so the schedule applies on day one rather than requiring guesswork from a generic national guide.
