These are 50%-probability averages modeled from Nashville's USDA hardiness zone and regional climate normals — not a single-station reading.

Plant tender crops (tomatoes, peppers, basil) once both soil and night temperatures are consistently warm — a thermometer beats the calendar.
Growing season in Nashville
Nashville, Tennessee sits in USDA Zone 7b, with roughly 203 frost-free days between an average last spring frost around April 8 and a first fall frost around October 28. That is a long season — succession-sow through summer and run a full fall crop; heat-sensitive greens still need spring/autumn timing. Nashville lies near 36.2°N; higher-latitude gardens get longer midsummer days but a tighter shoulder season at this zone. As a large metro, the built-up core typically runs up to half a zone warmer than outlying suburbs through the urban heat-island effect — sheltered city gardens often push tender crops a little earlier than the average suggests.

Local microclimate notes
Zone tables give you the average — but Nashvillegardens vary. South-facing walls and paved areas can run a full half-zone warmer than the published rating. Low-lying spots, frost pockets, and shaded north sides can run colder. If you've gardened here a few seasons, your own frost record — the last time you actually got frost damage — beats any national average.
Source and methodology
Hardiness zone from the USDA Plant Hardiness Zone Map (2023 revision). Frost-date and growing-season figures are modeled from Nashville's USDA hardiness zone and regional NOAA 1991-2020 climate normals — zone-level estimates, not a per-station record, so treat them as planning guidance and confirm against your own local frost history. Crop recommendations draw on US Cooperative Extension references, curated by the Growli editorial team. Last reviewed June 2026.
