Gardening in El Paso
El Paso's gardening straddles two countries and two traditions — Chihuahuan desert agriculture from the south and Texan practicality from the north. The Franklin Mountains bisect the city, creating microclimates and windbreaks. At 3,700 feet elevation, El Paso is cooler than its desert reputation suggests.
Desert sun, mountain winds, and Rio Grande water define El Paso gardening. The 240-day growing season is long, but summer heat above 100°F limits what grows from June through August. The alkaline, caliche-laced soil needs amendment that most Texas cities don't require. Water from the Rio Grande irrigation system makes food production possible in what is technically one of the driest cities in America.
El Paso's binational food culture means that backyard gardens grow chiles, tomatillos, and herbs that cross the border in both directions. The Ysleta and Socorro communities have been irrigating from the Rio Grande since the 1680s. UTEP's Chihuahuan Desert Gardens prove that beauty and food production both thrive in this unlikely landscape.
What This Means for El Paso Gardeners
The average last spring frost in El Paso is around March 15, and the average first fall frost arrives around November 10. That gives you approximately 240 frost-free days to work with.
That's a generous season. You have time for full-size tomatoes, long-season peppers, and even watermelons without the anxiety of racing the frost. Start warm-season seeds indoors 6-8 weeks before your last frost to hit the ground running. Fall planting is your second opportunity — garlic, kale, lettuce, and broccoli all go in 8-10 weeks before your first frost for harvest into late autumn.
These dates are based on NOAA 30-year Climate Normal data for the El Paso area. Your actual frost dates could shift 2-3 weeks in either direction in any given year. Learn more about our data sources.

Recommended starting points: tomatoes, peppers, beans, cucumbers, squash, garlic, kale, and sunflowers.
