When to Plant Vegetables in Tennessee

Last spring frost (median)

Growing season

~207 days

Across Tennessee, the median last frost falls around Apr 6 and the median first fall frost around Oct 30, from NOAA's 1991-2020 climate normals for the weather station nearest each of the state's ZIP codes. Half of years have a later last frost; 1 year in 10 is later than about Apr 21. Every date in the table below is calculated directly from those two dates using standard, extension-verified planting-offset rules, and the ZIP box recalculates it for your own station.

Below: the median across Tennessee’s 636 ZIP codes, each from its nearest NOAA weather station (1991-2020 records). Enter yours to recalculate the table for your own station.

Tennessee Planting Calendar

Crop Method Spring window Fall window
Tomatoes (Frost-sensitive) Start Indoors
Start indoors: Feb 9 - Feb 23
Transplant outdoors: Apr 13 - Apr 20
Transplant once nighttime lows are reliably above 50°F, not just after the calendar frost date.
None
Peppers (Frost-sensitive) Start Indoors
Start indoors: Jan 26 - Feb 9
Transplant outdoors: Apr 20 and later
Peppers want warmer soil than tomatoes -- when in doubt, wait the extra week.
None
Cucumbers (Frost-sensitive) Direct SowTransplant
Apr 13 - Apr 20
The real trigger is soil temperature (70°F+ at 1 inch deep), not the calendar -- this window is a practical estimate of when that soil temperature typically arrives after the last frost.
None
Beans (Frost-sensitive) Direct Sow
Apr 6 - Apr 13
Bean seed rots in cold, wet soil -- wait until the soil has warmed to at least 60°F.
None
Lettuce (Frost-tolerant) Direct Sow
Mar 9 - Mar 23
Cold-tolerant -- a good candidate for succession sowing every 2-3 weeks through spring.
Sow by Aug 27 - Sep 6
Carrots (Frost-tolerant) Direct Sow
Mar 2 - Mar 23
None
Squash / zucchini (Frost-sensitive) Direct SowTransplant
Apr 6 - Apr 13
Squash doesn’t tolerate cold -- wait for soil to reach about 70°F.
None
Broccoli (Frost-tolerant) Start Indoors
Feb 9 - Feb 23
Sow by Jul 28 - Aug 7
Spinach (Frost-tolerant) Direct Sow
Feb 23 - Mar 9
Sow as soon as the soil can be worked -- extension sources cite anywhere from 2-8 weeks before last frost depending on region; this is a middle estimate.
Sow by Aug 17 - Aug 27
Peas (Frost-tolerant) Direct Sow
Feb 23 - Mar 9
Cold-tolerant -- sow as soon as the soil can be worked.
None
Onions (sets or transplants) (Frost-tolerant) Transplant
Mar 9 - Mar 23
This window is for long-day onion varieties, the standard choice across most of the US. Gardeners in the Deep South growing short-day varieties follow a different fall/winter planting schedule.
None
Radishes (Frost-tolerant) Direct Sow
Feb 23 - Mar 9
Fast-maturing -- a reliable succession crop every 1-2 weeks through spring.
None
Corn (Frost-sensitive) Direct Sow
Apr 6 - Apr 13
Needs soil temperature of at least 50°F to germinate, with 65-75°F optimal for even germination.
None
Pumpkins (Frost-sensitive) Direct Sow
Apr 6 - Apr 13
Soil should reach about 65-70°F. If timing for a fall harvest target, count backward from your target date using the variety’s days-to-maturity instead of using this spring window.
None
Beets (Frost-tolerant) Direct Sow
Mar 9 - Mar 23
None
Cabbage (Frost-tolerant) Start Indoors
Feb 9 - Feb 23
None
Cauliflower (Frost-tolerant) Start Indoors
Feb 9 - Feb 23
Extension sources vary more on this crop than most (some cite as few as 4 weeks, others up to 10) -- this range is a defensible middle estimate, usually grown on the same schedule as cabbage.
None
Kale (Frost-tolerant) Direct Sow
Feb 23 - Mar 9
Sow by Aug 27 - Sep 6
Basil (Frost-sensitive) Start Indoors
Start indoors: Feb 9 - Feb 23
Transplant outdoors: Apr 20 and later
Frost-sensitive, unlike the cold-tolerant crops above -- transplant only after ALL frost risk has passed and soil has warmed to 60°F or more.
None

When to start, when to plant, how far apart.

Understanding Your Planting Windows

These windows come from a simple, real calculation: take Tennessee's median last-frost and first-frost dates, then apply fixed, extension-verified offset rules for each crop (for example, "start tomato seeds indoors 6-8 weeks before your last frost"). Because the offset rules are the same nationwide but Tennessee's actual frost dates are specific to Tennessee, the resulting dates are genuinely Tennessee's own, not a generic template.

These are statewide medians, though, and your own yard may run warmer or colder depending on elevation, urban heat, or microclimate. Enter your ZIP code in the box at the top of the page for your nearest station's dates. For Tennessee's full zone range from coldest to warmest areas, see the Tennessee Growing Zone page.

Sources & further reading

Frost dates come from NOAA NCEI's U.S. Climate Normals, 1991-2020: for each of Tennessee's ZIP codes, the median last and first 32°F dates at the nearest weather station (an airport station within 15 miles where there is one), with ZIP code points from the U.S. Census Bureau's 2023 ZCTA Gazetteer. The same station data drives our Frost Date Calculator. Planting-offset rules are drawn from US Cooperative Extension sources including UGA, UMN, NC State, Utah State, Iowa State, Penn State, and UConn Extension, cited crop-by-crop in the table above. For more on how we build and verify reference data across this site, see our methodology page.
