Soddy-Daisy, Tennessee, sits in USDA hardiness zone 7b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Crops well matched to these conditions include cabbage, prickly pear, california poppy, and collard greens — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Soddy-Daisy, 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 Soddy-Daisy 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 Soddy-Daisy
Each reading below is measured for Soddy-Daisy itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredSoddy-Daisy runs about 241 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.

Winter hardiness
MeasuredSoddy-Daisy sits in USDA hardiness zone 7b.
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 Soddy-Daisy is in

Every plant below cleared Soddy-Daisy's own zone 7b and its 241-day season. Each card opens that plant's Tennessee profile. How we score.






























Is it too late to plant in Soddy-Daisy?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 18; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 18 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 14 — long-season crops need about 90 days of runway, quick greens only 30. With a season this long, “too late” mostly means “switch crops” — second sowings and a full fall garden are the norm, with garlic closing the year.

A note from Gnorman
What an experienced grower watches for around here
In and around Soddy-Daisy, two things run higher than the national average within ~10 miles of Soddy-Daisy — Superfund (3 sites) and Underground Storage Tanks (148 sites). That's not a problem with your land — it's information about it.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Soddy-Daisy
Everything above resolves to Soddy-Daisy as a whole — one PHZM band and one 28°F frost record, read across 15K acres. 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 Soddy-Daisy
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 Soddy-Daisy’s own record; 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.

Common questions about Soddy-Daisy
When does frost risk typically end in Soddy-Daisy?
The last hard freeze (28°F) in Soddy-Daisy typically lands around Mar 18, 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 Apr 8.
When is the first frost in Soddy-Daisy?
The first hard freeze (28°F) in Soddy-Daisy typically arrives around Nov 14, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 31, so the watching starts about Oct 15 — about 241 days after the spring freeze cleared.
How long is the growing season in Soddy-Daisy?
Measured between 28°F hard freezes, Soddy-Daisy sees about 241 frost-free days — roughly Mar 18 through Nov 14, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 8 to Oct 31, about 206 days.
Is the soil safe to grow vegetables in Soddy-Daisy?
The federal record around Soddy-Daisy is a meaningful one — 211 documented sites, mostly Underground Storage Tanks entries (148), the nearest Underground Storage Tanks record about 0.7 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 Soddy-Daisy?
From about Oct 15 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 14 (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 14. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
