Midland gardening questions

When is the last frost in Midland, TX?

Plan around Apr 3. At NOAA's Midland 4 ENE, TX station, 5.2 mi from the city center, there is a 30% chance of a 32°F frost after that date. Half of springs have their last frost by Mar 26, and after Apr 15 the risk drops to about 1 in 10. A hard freeze (28°F) usually ends earlier, around Mar 10. The 90% and 10% dates are 42 days apart, close to the 36-day median for cities on this site.

When should I plant tomatoes in Midland, TX?

Start seeds indoors Feb 6 – Feb 20 and set transplants outside Apr 10 – Apr 24, once nights stay above 50°F and the soil is near 60°F. That leaves 214 days between the 30% frost dates, enough for most varieties including 80–85-day slicers. More: tomato planting dates by zone.

How long is the growing season in Midland?

About 226 days without a 32°F frost in a typical (median) year. In 9 years out of 10 the season lasts at least 200 days, and in 1 year in 10 it runs 251 days or more. In fall there is a 10% chance of frost by Oct 25 and a 30% chance by Nov 3. That ranks 53rd longest of 55 Texas cities on this site.

When should I plant a fall garden in Midland?

Count back from the first fall frost (Nov 3): transplant broccoli Aug 11 – Aug 25; sow kale Aug 25 – Sep 22; sow lettuce Aug 25 – Sep 22; sow radishes Sep 22 – Oct 20. Hardy crops keep growing through light frosts; the median 28°F hard freeze here is Nov 18. How the math works: succession and fall planting.

Did Midland's hardiness zone change on the 2023 map?

Yes. Most of Midland was zone 8a on the 2012 map and is zone 8b on the 2023 map — half a zone warmer, like about 56% of U.S. ZIP codes. The shift comes from a newer 1991–2020 averaging period plus more weather stations and better mapping; it does not mean last frost comes earlier. Why the 2023 map is warmer.

Is all of Midland in zone 8b?

No. Zone 8b covers about 57% of the city's land; the rest is in 8a (43%), measured across the city's 5 ZIP codes. Check your own ZIP code in the table above or with the ZIP lookup.
