Gardening in Gainesville
UF's college town has the agricultural research to back up its food garden ambitions. The Florida Institute of Food and Agricultural Sciences (IFAS) makes Gainesville one of the most knowledge-rich garden cities in the South.
Zone 9a with north-central Florida's transition climate — cold enough for blueberries, warm enough for citrus. Your 278-day growing season bridges the Deep South and subtropical Florida.
UF/IFAS is one of the premier agricultural research institutions in the world. Gainesville gardeners have access to research-based growing advice that most cities can only dream about. The Alachua County Farmers Market is the weekly gathering.
What This Means for Gainesville Gardeners
The average last spring frost in Gainesville is around February 20, and the average first fall frost arrives around November 25. That gives you approximately 278 frost-free days to work with.
278 days is a long, productive season that supports two full rounds of warm-season crops plus continuous cool-season production through your mild winter. Most frost-sensitive crops can be transplanted by February 20, giving them months to produce before fall. Your winter garden is the real advantage — growing fresh vegetables in December and January while northern gardeners browse seed catalogs.
These dates are based on NOAA 30-year Climate Normal data for the Gainesville area. Your actual frost dates could shift 2-3 weeks in either direction in any given year. Learn more about our data sources.

Recommended starting points: tomatoes, peppers, beans, cucumbers, squash, garlic, kale, and sunflowers.
