Planting dates for Nashville
Worked out from the median frost dates (and, for warm-season crops, NOAA’s normal night lows) with the same crop rules as the calendar below. Tap any crop there for its dates.
Frost alone would allow transplanting from Apr 8, but the normal night low here only reaches 50°F (10°C) about Apr 25, so they go out then, started indoors 9 weeks before. Transplant when nights stay above 50°F (10°C).
Frost alone would allow transplanting from Apr 15, but the normal night low here only reaches 50°F (10°C) about Apr 25, so they go out then, started indoors 12 weeks before. Loves warm soil, 65°F+ (18°C+).
3–6 weeks before the last frost, and again 8–10 weeks before the first fall frost. Sow as soon as soil can be worked (40°F/4°C+).
From 4 weeks before to 2 weeks after the last frost, and 4–8 weeks before the first fall frost. Bolts in heat; sow small batches often.
2 weeks before to 3 weeks after the first fall frost. Plant cloves in fall; harvest next summer when lower leaves brown.

The median first fall freeze (32°F) is Oct 31. In 8 of 10 years it falls between Oct 18 and Nov 13, and there is only a 1-in-10 chance of a freeze before Oct 18. That leaves a median of 213 frost-free days.
Using FrostLine’s crop rules with the median last frost of Apr 1 and NOAA’s normal night lows: start tomato seeds indoors Feb 21 – Mar 7 and transplant them outside Apr 25 – May 16. Frost alone would allow Apr 8, but nights here only average 50°F (10°C) from about Apr 25.
No. They are long-term averages, not a forecast for this year. Your own garden can differ by one to three weeks with elevation, slope, wind and how built-up it is. Check the 10-day forecast before setting out tender plants, and enter your own ZIP for the nearest station.
How it works: each ZIP is matched to the nearest NOAA station with freeze records. More on our method.
