What this means for growing in Shorewood-Tower Hills-Harbert
Each reading below is measured for Shorewood-Tower Hills-Harbert itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredShorewood-Tower Hills-Harbert runs about 218 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
MeasuredShorewood-Tower Hills-Harbert sits in USDA hardiness zone 6b.
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 Shorewood-Tower Hills-Harbert?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 13; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 10 (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. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.

A note from Gnorman
What an experienced grower watches for around here
In and around Shorewood-Tower Hills-Harbert, two things run higher than the national average within ~10 miles of Shorewood-Tower Hills-Harbert — Superfund (5 sites) and Underground Storage Tanks (144 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
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 Shorewood-Tower Hills-Harbert
Everything above resolves to Shorewood-Tower Hills-Harbert as a whole — one PHZM band and one 28°F frost record, read across 3K 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 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 Shorewood-Tower Hills-Harbert
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 Shorewood-Tower Hills-Harbert’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 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.

Common questions about Shorewood-Tower Hills-Harbert
When does frost risk typically end in Shorewood-Tower Hills-Harbert?
The last hard freeze (28°F) in Shorewood-Tower Hills-Harbert typically lands around Apr 10, 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 May 1.
When is the first frost in Shorewood-Tower Hills-Harbert?
The first hard freeze (28°F) in Shorewood-Tower Hills-Harbert 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 218 days after the spring freeze cleared.
How long is the growing season in Shorewood-Tower Hills-Harbert?
Measured between 28°F hard freezes, Shorewood-Tower Hills-Harbert sees about 218 frost-free days — roughly Apr 10 through Nov 14, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 1 to Oct 31, about 183 days.
Is the soil safe to grow vegetables in Shorewood-Tower Hills-Harbert?
The federal record around Shorewood-Tower Hills-Harbert is a meaningful one — 230 documented sites, mostly Underground Storage Tanks entries (144), the nearest Underground Storage Tanks record about 0.3 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 Shorewood-Tower Hills-Harbert?
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.
