Augusta, GA Frost Dates
Average frost dates, USDA hardiness zone, and growing season length for Augusta, Georgia.
Gardening in Augusta
Augusta's Masters Tournament fame overshadows a gardening heritage that goes back to the colonial era. The Augusta Canal and Savannah River corridors provide fertile growing ground that's been cultivated for centuries.
The Savannah River valley creates warm, fertile conditions — your 240-day growing season is one of the longest in Georgia. The transition from Piedmont clay to Coastal Plain sand happens in the Augusta metro, giving different neighborhoods noticeably different soil types.
The Masters isn't the only thing that blooms beautifully in Augusta every April — the city's azaleas and gardens are legendary. The Riverwalk Augusta and the city's historic neighborhoods have maintained garden traditions since before the tournament existed.
What This Means for Augusta Gardeners
The average last spring frost in Augusta is around March 15, and the average first fall frost arrives around November 10. That gives you approximately 240 frost-free days to work with.
That's a generous season. You have time for full-size tomatoes, long-season peppers, and even watermelons without the anxiety of racing the frost. Start warm-season seeds indoors 6-8 weeks before your last frost to hit the ground running. Fall planting is your second opportunity — garlic, kale, lettuce, and broccoli all go in 8-10 weeks before your first frost for harvest into late autumn.
These dates are based on NOAA 30-year Climate Normal data for the Augusta area. Your actual frost dates could shift 2-3 weeks in either direction in any given year. Learn more about our data sources.
What to Grow in Augusta
Augusta's 240-day growing season is generous — long enough for two full growing windows (spring and fall) with warm-season crops between them. You can grow the full range of vegetables, herbs, and flowers with proper timing. Focus on heat-tolerant varieties for midsummer and cool-season crops for extended fall harvests. Recommended starting points: tomatoes, peppers, beans, cucumbers, squash, garlic, kale, and sunflowers.
