Harding Gill Tract, Texas, sits in USDA hardiness zone 10a — a zone band wide enough that plant choice, not possibility, is the interesting question.
These conditions suit okra, meyer lemon, california poppy, and artichoke — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

What this means for growing in Harding Gill Tract
Each reading below is measured for Harding Gill Tract itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsHarding Gill Tract runs about 341 days between hard freezes (read from Hidalgo County, the closest normal to Harding Gill Tract) — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.

Winter hardiness
MeasuredHarding Gill Tract sits in USDA hardiness zone 10a.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

Is it too late to plant in Harding Gill Tract?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Jan 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 16 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 23 — long-season crops need about 90 days of runway, quick greens only 30. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.

What an experienced grower watches for around here
In and around Harding Gill Tract, Underground Storage Tanks runs higher than the national average — 47 sites within ~10 miles of Harding Gill Tract. That's not a problem with your land — it's information about it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Harding Gill Tract
Everything above resolves to Harding Gill Tract as a whole — one PHZM band, read across 701 acres, with hard-freeze dates borrowed from Hidalgo County’s record because no 30-year normal resolves at this town’s own centroid. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Harding Gill Tract
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Hidalgo County’s record, because none resolves here; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Harding Gill Tract
When does frost risk typically end in Harding Gill Tract?
The last hard freeze (28°F) in Harding Gill Tract typically lands around Jan 16, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Feb 6.
When is the first frost in Harding Gill Tract?
The first hard freeze (28°F) in Harding Gill Tract typically arrives around Dec 23, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 9, so the watching starts about Nov 23 — about 341 days after the spring freeze cleared.
How long is the growing season in Harding Gill Tract?
Measured between 28°F hard freezes, Harding Gill Tract sees about 341 frost-free days — roughly Jan 16 through Dec 23, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 6 to Dec 9, about 306 days.
Is the soil safe to grow vegetables in Harding Gill Tract?
The federal record around Harding Gill Tract shows 62 documented sites, mostly Underground Storage Tanks entries (47), the nearest Underground Storage Tanks record about 3.6 miles out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Harding Gill Tract?
From about Nov 23 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Dec 23 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Dec 23. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
