Ravenna, Texas, sits in USDA hardiness zone 8a — a zone band wide enough that plant choice, not possibility, is the interesting question.
Among the crops suited to this profile: cabbage, fig, california poppy, and collard greens. The site-level story — soil, sun, drainage — decides the rest.
Even in Ravenna, 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 Ravenna 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 Ravenna
Each reading below is measured for Ravenna itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsRavenna runs about 264 days between hard freezes (read from Fannin County, the closest normal to Ravenna) — 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
MeasuredRavenna sits in USDA hardiness zone 8a.
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 Ravenna is in
Ravenna sits in the East Central Texas Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Ravenna's own centroid, and it is not what its county reads: Fannin County is mostly Texas Blackland Prairies. The wider page above you is answering a different question about different ground.

Is it too late to plant in Ravenna?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Feb 3; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 3 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 22 — 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 Ravenna, Underground Storage Tanks runs higher than the national average — 106 sites within ~10 miles of Ravenna. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
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 Ravenna
Everything above resolves to Ravenna as a whole — one PHZM band, read across 771 acres, with hard-freeze dates borrowed from Fannin 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 Ravenna
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 Fannin 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 Ravenna
When does frost risk typically end in Ravenna?
The last hard freeze (28°F) in Ravenna typically lands around Mar 3, 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 24.
When is the first frost in Ravenna?
The first hard freeze (28°F) in Ravenna typically arrives around Nov 22, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 8, so the watching starts about Oct 23 — about 264 days after the spring freeze cleared.
How long is the growing season in Ravenna?
Measured between 28°F hard freezes, Ravenna sees about 264 frost-free days — roughly Mar 3 through Nov 22, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 24 to Nov 8, about 229 days.
Is the soil safe to grow vegetables in Ravenna?
The federal record around Ravenna is a meaningful one — 123 documented sites, mostly Underground Storage Tanks entries (106), the nearest Underground Storage Tanks record about 0.2 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 Ravenna?
From about Oct 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 Nov 22 (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 22. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
