Myrtle Springs, Texas, sits in USDA hardiness zone 8b — a zone band wide enough that plant choice, not possibility, is the interesting question.
On paper, cabbage, fig, california poppy, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Myrtle Springs, no two yards are alike.

What this means for growing in Myrtle Springs
Each reading below is measured for Myrtle Springs itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsMyrtle Springs runs about 284 days between hard freezes (read from Van Zandt County, the closest normal to Myrtle Springs) — 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
MeasuredMyrtle Springs sits in USDA hardiness zone 8b.
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.

The kind of country Myrtle Springs is in
Myrtle Springs sits in the East Central Texas Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Myrtle Springs's own centroid rather than borrowed from Van Zandt County.

Is it too late to plant in Myrtle Springs?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 22; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 19 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 30 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

What an experienced grower watches for around here
In and around Myrtle Springs, two things run higher than the national average within ~10 miles of Myrtle Springs — PFAS (6 sites) and Underground Storage Tanks (123 sites). That's not a problem with your land — it's information about 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.

Your land is one point inside Myrtle Springs
Everything above resolves to Myrtle Springs as a whole — one PHZM band, read across 5K acres, with hard-freeze dates borrowed from Van Zandt 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 Myrtle Springs
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 Van Zandt 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 Myrtle Springs
When does frost risk typically end in Myrtle Springs?
The last hard freeze (28°F) in Myrtle Springs typically lands around Feb 19, 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 Mar 12.
When is the first frost in Myrtle Springs?
The first hard freeze (28°F) in Myrtle Springs typically arrives around Nov 30, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 16, so the watching starts about Oct 31 — about 284 days after the spring freeze cleared.
How long is the growing season in Myrtle Springs?
Measured between 28°F hard freezes, Myrtle Springs sees about 284 frost-free days — roughly Feb 19 through Nov 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 12 to Nov 16, about 249 days.
Is the soil safe to grow vegetables in Myrtle Springs?
The federal record around Myrtle Springs is a meaningful one — 167 documented sites, mostly Underground Storage Tanks entries (123), the nearest Nitrate record about 0.9 miles out — 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.
How do I protect my plants from frost in Myrtle Springs?
From about Oct 31 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 Nov 30 (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 Nov 30. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
