Is it too late to plant in De Baca County?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Feb 6; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 6 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 21 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.
Growing Challenges in New Mexico
What an experienced grower plans around here — each one has a move.
Very low rainfall requires irrigation for most crops
High-desert growing starts with the water plan — drip lines, deep mulch, and basins put scarce rain exactly where roots are.
High altitude UV intensity can burn tender transplants
Harden seedlings slowly and shade-cloth their first week out — high-desert sun is stronger than any indoor start prepares them for.
Alkaline soils limit plant selection without amendment
Test first: knowing your actual pH turns 'what won't grow' into a short, workable amendment list.
For cultivar selection, pest pressure, and planting-time guidance specific to New Mexico, the NMSU Cooperative Extension Service is the authoritative local source.

What an experienced grower watches for around here
In and around De Baca County, Nitrate runs higher than the national average — 64 sites nearby. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Frequently Asked Questions
What hardiness zone is De Baca County, New Mexico?
De Baca County sits in USDA hardiness zone 7a, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
Is it too late to plant in De Baca County?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Feb 6; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 6 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 21 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.
When does frost risk typically end in De Baca County?
The last hard freeze (28°F) in De Baca County typically lands around Mar 6, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.
How long is the growing season in De Baca County?
Measured between 28°F hard freezes, De Baca County sees about 260 frost-free days — roughly Mar 6 through Nov 21, per NOAA 1991–2020 climate normals. Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.
What vegetables grow in De Baca County?
De Baca County's zone 7a supports a wide range — strong performers include Green Chile, Pecan, Pinon Pine, Prickly Pear, and Apache Plume. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.
Which hardiness zone is De Baca County, really?
Officially, De Baca County sits in USDA zone 7a (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.
Is the soil safe to grow vegetables in De Baca County?
The federal record around De Baca County is a meaningful one — 85 documented sites — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
Just moved to De Baca County — what should I know before planting?
Start with three facts. De Baca County sits in USDA zone 7a, which sets what survives winter; the last 28°F hard freeze typically clears around Mar 6, with about 260 frost-free days to work with (NOAA 1991–2020 climate normals); and 85 documented sites sit on the federal record here, so a soil test before food beds is the smart first step. From there, matching plants to your actual soil and sun is the fun part.
