El Paso gardening questions

When is the last frost in El Paso, TX?

Plan around Mar 9. At NOAA's El Paso Int'l Airport, TX station, 4.1 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 2, and after Mar 19 the risk drops to about 1 in 10. A hard freeze (28°F) usually ends earlier, around Feb 16. The 90% and 10% dates are 35 days apart, close to the 36-day median for cities on this site.

When should I plant tomatoes in El Paso, TX?

Start seeds indoors Jan 12 – Jan 26 and set transplants outside Mar 16 – Mar 30, once nights stay above 50°F and the soil is near 60°F. That leaves 250 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 El Paso?

About 261 days without a 32°F frost in a typical (median) year. In 9 years out of 10 the season lasts at least 237 days, and in 1 year in 10 it runs 284 days or more. In fall there is a 10% chance of frost by Nov 6 and a 30% chance by Nov 14. That ranks 25th longest of 55 Texas cities on this site.

When should I plant a fall garden in El Paso?

Count back from the first fall frost (Nov 14): transplant broccoli Aug 22 – Sep 5; sow kale Sep 5 – Oct 3; sow lettuce Sep 5 – Oct 3; sow radishes Oct 3 – Oct 31. Hardy crops keep growing through light frosts; the median 28°F hard freeze here is Dec 1. How the math works: succession and fall planting.

Did El Paso's hardiness zone change on the 2023 map?

Yes. Most of El Paso 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.

How does El Paso compare with Las Cruces, NM?

Both are in zone 8b. The typical last spring frost in El Paso (Mar 9) comes about 11 days earlier than in Las Cruces, NM (Mar 20), 39 miles away, and the first fall frost is Nov 14 versus Nov 7. The two cities use different NOAA stations.
