Indoor seed-starting dates by crop
Work backwards from an outdoor target of Apr 22: the selected spring freeze date plus an editable seven-day delay.
These are transplant-growing windows, not a recommendation to plant every crop on the same day. Adjust the outdoor target for your crop, soil temperature and local conditions.
| Crop | Time indoors | Illustrative sowing window | Your plan |
|---|---|---|---|
| Tomatoes | 5–6 weeks | Mar 11 – Mar 18 | Plan tomatoes → |
| Peppers | 8–10 weeks | Feb 11 – Feb 25 | Plan peppers → |
| Eggplant | 8–10 weeks | Feb 11 – Feb 25 | Plan eggplant → |

“Frost date” is common gardening shorthand. These NOAA figures describe air temperatures reaching 32°F; frost on leaves can occur under different conditions. The two tail probabilities do not give the probability of a completely freeze-free season.
Frost date questions
How we use the dataWhen is the last frost in Levelland?
The median last 32°F spring freeze at the selected station is April 9. The more cautious 10% date is April 25. Neither date predicts the weather in a particular year.
Can I plant tomatoes on the last frost date?
Use the date as one input. Tomatoes need warm soil, suitable nighttime temperatures, and hardening off. A 50% historical date still carries substantial freeze risk. Check your seed instructions, local extension guidance and current forecast.
Why do other websites show a different date?
Sites may use another station, reference period, temperature threshold or probability. This guide identifies the station and shows three probabilities so you can compare like with like.
