Your yard isn't the whole zone.
Pumpkin is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is. A typical Texas site runs ~274 frost-free days, but that is a state median, not your yard: slope, trees, and low spots move the last-frost date across a single parcel. Enter your address and we'll score pumpkin against your land's actual frost dates, sun, and soil.

Texas is not one climate
A single Texas answer averages 254 counties whose growing seasons are 146 days apart — from 197 frost-free days in Dallam County to 343 in Kenedy County. Which end of that your land sits nearer changes what pumpkin can finish before the first hard freeze.
The middle half of 254 counties runs 252–297 days, with a median of 274 days — a 146-day span end to end.

When to Plant Pumpkin 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.
When to start the seed
Pumpkin is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — Texas'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.
Days to maturity vs. the window
At 110 days to maturity (Growable Ground Plant Database), counting from the last hard freeze it ripens with 141 days to spare even in Texas's tightest freeze scenario — room for a later start or a second sowing.
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 pumpkin survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Pumpkin wants 40+ 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
Pumpkin needs ~1100 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
Pumpkin tolerates a wide pH range (pH 4.5-8.3) — 3.8 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 6.8 — 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.

Drainage: FAO ECOCROP, with the remaining rows from other published sources or Growable Ground compilation. Texas soil profile from USDA NRCS SSURGO.

Before you plant pumpkin for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before pumpkin goes in. What follows is Texas’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Texas — and how to grow with it.
We checked the federal record across Texas — 93,167 documented sites across 8 of the 9 source types we track.
The most significant on record: 480 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Texas carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

Highest-Severity Sites
A note from Gnorman
What an experienced grower watches for around here
In and around Texas, two things run higher than the national average across Texas — PFAS (1,103 sites) and Underground Storage Tanks (61,246 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
What Else to Consider for Pumpkin 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 pumpkin — is covered on the Texas growing guide.
Timing shifts within Texas
Pumpkin needs about 40 days of frost-free season to complete its cycle. Even Dallam County — Texas’s shortest season at 197 frost-free days — clears that by 157 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 pumpkin about 234 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"). Pumpkin's 40-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Pumpkin draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, pumpkin can only work that bloom inside Texas's frost window — roughly 274 days, opening after the last 28°F freeze (Feb 10 - Mar 12) and closing at the first (Nov 18 - Dec 4), per NOAA Regional Climate Centers ACIS, 1991-2020.
Texas Cooperative Extension
For Texas-specific cultivar recommendations, planting calendars, and pest pressure for pumpkin, 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 Pumpkin native to Texas?
No — the USDA PLANTS Database lists Pumpkin 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.

What pests threaten pumpkin in Texas?
Squash bug and squash vine borer are documented in Texas, and they hit pumpkin where it counts. Here is what each one actually does — and the move that beats it.
Squash bug
Act on thisSquash bugs primarily attack squash and pumpkins, and the plants most at risk are the youngest and the ones in flower — the University of Minnesota notes feeding can kill young plants outright, while a larger, sturdier plant shrugs it off.
What to do: Go after where they sleep, not just the bugs. Crush the bronze egg clusters on the leaf undersides in the vein angles, drop nymphs and adults into soapy water, and clear plant debris through the season and again in fall to strip out overwintering shelter. Where squash bugs are a consistent problem, skip straw mulch — it gives them the night shelter they are looking for.
Here: In Texas that second clean-up lands around Nov 18 - Dec 4, when the first 28°F freeze typically ends the pumpkin — pulling the vines then is what strips the overwintering shelter, and leaving them is what stocks next season.

Squash vine borer
Act on thisThe wilt you notice is the larva already inside the stem. The University of Illinois puts it plainly: the squash vine borer cannot complete its development except in squash or pumpkins — and Hubbard and acorn types are the ones Kentucky and Wisconsin name as most susceptible.
What to do: Two moves beat it, and both are about timing. Float a row cover over the plants when the vines start to run — late June or early July for non-vining types — anchor the sides, and keep it on for about two weeks after the first adult moth is seen; take it off once flowers open so bees can work. Then sow a second planting of summer squash in early July: those plants mature after the moths have finished laying and come through undamaged.
Here: The escape works here. Texas's ~274 frost-free days carry two ~110-day pumpkin crops, so a later sowing has room to finish after the moths have stopped laying.

Common Questions About Growing Pumpkin in Texas
When can I plant Pumpkin 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). 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.
Can Pumpkin mature before first frost in Texas?
Yes — Pumpkin matures in 110 days (Growable Ground Plant Database), and Texas's dependable hard-freeze-free window runs 251 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 141 days of margin. Plant once the last hard freeze has passed — two to three weeks later for anything tender — and it ripens ahead of the first fall freeze.
What hardiness zone is Pumpkin grown in across Texas?
Texas spans USDA hardiness zones 6b-10b (USDA ARS PHZM 2023). Pumpkin carries a range of zones 3-11, 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). Pumpkin needs 40+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Pumpkin native to Texas?
No — the USDA PLANTS Database lists Pumpkin 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 Pumpkin in Texas?
Pumpkin tolerates pH 4.5-8.3 and well (dry spells) drainage (FAO ECOCROP). That is a 3.8-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.
Will Pumpkin actually grow on my specific land in Texas?
