Conditional — Some Areas
malanga (zones 9-12) reaches only part of Texas (6b-10b): zones 9-10 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Texas spans zones 6b-10b, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score malanga against your land's actual soil, sun, and frost.

When to Plant Malanga in Texas
The frost window
Across Texas, the last spring hard freeze (28°F) clears between Feb 10 and Mar 12, and the first fall hard freeze lands between Nov 18 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 251-day window you can count on — up to 297 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.
Frost tenderness
Malanga is frost-tender — its listed minimum temperature is 50°F (USDA PLANTS Database) — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does.
Days to maturity vs. the window
At 270 days to maturity (USDA PLANTS Database), the fit is tight: Texas's dependable window runs 251 days. Starting seeds indoors and transplanting at the front of the window banks the difference.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. 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 malanga survives winter in part of Texas, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Malanga wants 120+ frost-free days; a typical Texas site sees ~274 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Malanga needs ~4000 GDD (base 50°F) to ripen. The state median runs ~5834 GDD (from PRISM 1991-2020 climate normals), so Texas's typical season clears that easily.
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
Malanga tolerates a wide pH range (pH 4.5-7.8) — 3.3 units, acid ground through alkaline — so soil acidity is rarely what limits it in Texas. 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 Texas soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Texas site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Malanga in Texas
Zone compatibility tells you about winter cold survival — but Texas growers also need to think about:
Extreme heat (100F+ days) stresses many crops from June through September
Rainfall varies dramatically — 8 inches in west TX to 56 inches in east TX
Heavy black clay (Blackland Prairie) is difficult to work and drains poorly
Flash drought conditions can develop rapidly even in wet years
What to actually do about these — and the constraints that apply to every Texas grower, not just malanga — is covered on the Texas growing guide.
Timing shifts within Texas
Malanga needs about 120 days of frost-free season to complete its cycle. Even Dallam County — Texas’s shortest season at 197 frost-free days — clears that by 77 days, so season length isn’t the constraint anywhere in Texas. What varies is your own parcel.
Across Texas’s 254 counties the frost-free season runs from 197 days in Dallam County to 343 days in Kenedy County — a spread of 146 days, which is why a single statewide planting date misleads. The median Texas county sees 274 frost-free days, leaving malanga about 154 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"). Malanga's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Texas Fits Best
Even within Texas's zones 6b-10b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for malanga (USDA PHZM 2023):

For Texas-specific cultivar recommendations, planting calendars, and pest pressure for malanga, the canonical source is Texas A&M AgriLife Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Malanga native to Texas?
No — the USDA PLANTS Database lists Malanga as introduced rather than native in the Lower 48, so it is not part of Texas's native flora. It grows here as a garden plant; pairing it with a few Texas natives keeps local pollinators fed too.

Common Questions About Growing Malanga in Texas
When can I plant Malanga in Texas?
Texas's last spring hard freeze (28°F) clears between Feb 10 and Mar 12, and the first fall hard freeze lands between Nov 18 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). Malanga is frost-tender — its listed minimum temperature is 50°F (USDA PLANTS Database) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
Can Malanga mature before first frost in Texas?
It's close: Malanga needs 270 days to mature (USDA PLANTS Database) against Texas's 251-day dependable window (NOAA Regional Climate Centers ACIS, 1991-2020). Start seeds indoors and transplant once the last hard freeze has passed to bank the missing days.
What hardiness zone is Malanga grown in across Texas?
Texas spans USDA hardiness zones 6b-10b (USDA ARS PHZM 2023). Malanga carries a range of zones 9-12, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Texas site have?
A typical Texas site sees ~274 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Malanga needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Malanga native to Texas?
No — the USDA PLANTS Database lists Malanga as introduced rather than native in the Lower 48, so it is not part of Texas's native flora. It grows here as a garden plant; pairing it with a few Texas natives keeps local pollinators fed too.
How should I amend the soil for Malanga in Texas?
Malanga tolerates pH 4.5-7.8 and well (dry spells) drainage (FAO ECOCROP). That is a 3.3-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Texas site — amend for drainage and organic matter first.
