Unlikely — Zone Mismatch
Nadi blue grass (zones 10-13) does not overlap with New Mexico's zone range (5a-9a). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
Nadi Blue Grass is hardy to zone 10, and the warmest ground in New Mexico is zone 9 — 1 zone short. Planted in open ground it will not survive a New Mexico winter. To grow it here, grow nadi blue grass in a hoop house or unheated greenhouse — its modeled 1.5-zone lift covers this gap.

New Mexico is not one climate
A single New Mexico answer averages 33 counties whose growing seasons are 120 days apart — from 144 frost-free days in Catron County to 264 in Doña Ana County. Which end of that your land sits nearer changes what nadi blue grass can finish before the first hard freeze.
The middle half of 33 counties runs 186–221 days, with a median of 209 days — a 120-day span end to end.

Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where Nadi Blue Grass Stands in New Mexico
Nadi Blue Grass is rated for zones 10–13 — a cold floor USDA puts at 30 to 40°F. No New Mexico county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about New Mexico winters, not about nadi blue grass.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.

When to Plant Nadi Blue Grass in New Mexico
The frost window
Across New Mexico, the last spring hard freeze (28°F) clears between Mar 31 and Apr 19, and the first fall hard freeze lands between Oct 22 and Nov 9 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 186-day window you can count on — up to 223 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
When to start the seed
Nadi Blue Grass is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — New Mexico's dates above are the whole calendar for it. That makes the last-freeze date the binding constraint, and a warmer pocket of your own yard is worth more to this crop than it is to a transplanted one.
Timing tuned to sub-state frost dates — Catron County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says nadi blue grass does not survive a New Mexico winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on New Mexico under protection.
Frost-free days
Nadi Blue Grass wants 180+ frost-free days; a typical New Mexico site sees ~209 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Nadi Blue Grass tolerates a wide pH range (pH 5-8) — 3 units, acid ground through alkaline — so soil acidity is rarely what limits it in New Mexico. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5.5 and 7 — worth knowing before you decide whether a New Mexico soil test result is a problem or just a number. Drainage matters: this plant wants poorly (saturated >50% of year), well (dry spells). If your New Mexico site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
New Mexico's soils run mostly loam, but SSURGO maps the series, texture, and drainage under your exact parcel. Nadi Blue Grass needs about 7 inches of workable depth, so it is that horizon — not the surface — you are testing for. That map unit, not the state average, decides how nadi blue grass performs.

What Else to Consider for Nadi Blue Grass in New Mexico
Zone compatibility tells you about winter cold survival — but New Mexico growers also need to think about:
Very low rainfall requires irrigation for most crops
High altitude UV intensity can burn tender transplants
Alkaline soils limit plant selection without amendment
Growing nadi blue grass here specifically
Nadi Blue Grass wants pH 5.0–8.0 and rates to USDA zones 10–13, but New Mexico's soils are dominantly loam — the fit is decided by your parcel's own map unit, not the state average.
Match nadi blue grass to your parcel's SSURGO map unit — test pH and texture, and amend toward its 5.0–8.0 range. How to handle it →
What to actually do about these — and the constraints that apply to every New Mexico grower, not just nadi blue grass — is covered on the New Mexico growing guide.
Timing shifts within New Mexico
New Mexico isn't one climate. In Catron County, the last hard freeze (28°F) holds until about May 22 — roughly 43 days later than the recorded state median — so plant nadi blue grass to your county's window, not the statewide date.
Nadi Blue Grass needs about 180 days of frost-free season to complete its cycle. 26 of New Mexico’s 33 counties give it that outright. The tightest that does is Torrance County at 183 frost-free days — 3 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across New Mexico’s 33 counties the frost-free season runs from 144 days in Catron County to 264 days in Doña Ana County — a spread of 120 days, which is why a single statewide planting date misleads. The median New Mexico county sees 209 frost-free days, leaving nadi blue grass about 29 days of slack on a typical parcel — room for a second sowing where the season runs long.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Nadi Blue Grass's 180-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Common Questions About Growing Nadi Blue Grass in New Mexico
When can I plant Nadi Blue Grass in New Mexico?
New Mexico's last spring hard freeze (28°F) clears between Mar 31 and Apr 19, and the first fall hard freeze lands between Oct 22 and Nov 9 (NOAA Regional Climate Centers ACIS, 1991-2020). Time outdoor planting to after the last hard freeze for your specific site — a further two to three weeks for anything tender — and count back from those dates for transplant scheduling.
What hardiness zone is Nadi Blue Grass grown in across New Mexico?
New Mexico spans USDA hardiness zones 5a-9a (USDA ARS PHZM 2023). Nadi Blue Grass carries a range of zones 10-13, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical New Mexico site have?
A typical New Mexico site sees ~209 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Nadi Blue Grass needs 180+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Catron, the freeze-free season runs shorter than the state average, so verify your own county's window.
How should I amend the soil for Nadi Blue Grass in New Mexico?
Nadi Blue Grass tolerates pH 5-8 and poorly (saturated >50% of year), well (dry spells) drainage (FAO ECOCROP). That is a 3-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a New Mexico site — amend for drainage and organic matter first.
