Kemp, Texas, sits in USDA hardiness zone 8b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Growers here do well with cabbage, fig, california poppy, and collard greens — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in Kemp, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Kemp lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Kemp
Each reading below is measured for Kemp itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsKemp runs about 280 days between hard freezes (read from Kaufman County, the closest normal to Kemp) — 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
MeasuredKemp 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 Kemp is in
Kemp sits in the Texas Blackland Prairies — EPA Level III, inside the wider Great Plains. That is read at Kemp's own centroid rather than borrowed from Kaufman County.

Is it too late to plant in Kemp?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 23; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 20 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 27 — 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 Kemp, two things run higher than the national average within ~10 miles of Kemp — PFAS (3 sites) and Underground Storage Tanks (59 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.

Your land is one point inside Kemp
Everything above resolves to Kemp as a whole — one PHZM band, read across 1K acres, with hard-freeze dates borrowed from Kaufman County’s record because no 30-year normal resolves at this city’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 city 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 Kemp
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Kaufman 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 city grain anywhere on this page — there is no city-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 Kemp
When does frost risk typically end in Kemp?
The last hard freeze (28°F) in Kemp typically lands around Feb 20, 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 13.
When is the first frost in Kemp?
The first hard freeze (28°F) in Kemp typically arrives around Nov 27, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 13, so the watching starts about Oct 28 — about 280 days after the spring freeze cleared.
How long is the growing season in Kemp?
Measured between 28°F hard freezes, Kemp sees about 280 frost-free days — roughly Feb 20 through Nov 27, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 13 to Nov 13, about 245 days.
Is the soil safe to grow vegetables in Kemp?
The federal record around Kemp is a meaningful one — 78 documented sites, mostly Underground Storage Tanks entries (59), the nearest Underground Storage Tanks record about 0.1 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 Kemp?
From about Oct 28 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 27 (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 27. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
