Glencoe, Florida, sits in USDA hardiness zone 10a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
The conditions favor mango, tomato, orange, and sweet potato, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Glencoe, no two yards are alike.

What this means for growing in Glencoe
Each reading below is measured for Glencoe itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsGlencoe runs about 323 days between hard freezes (read from Volusia County, the closest normal to Glencoe) — 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
MeasuredGlencoe sits in USDA hardiness zone 10a.
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.
USDA PHZM 2023
The kind of country Glencoe is in
Glencoe sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Glencoe's own centroid rather than borrowed from Volusia County.
What Grows in Glencoe
Plants matched to Glencoe's USDA zones 10a, ordered by how much hardiness margin each has here — the ones with room to spare at both ends of this town's band lead. Each links to its full growing profile.
Is it too late to plant in Glencoe?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Jan 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 29 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 18 — long-season crops need about 90 days of runway, quick greens only 30. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.

A note from Gnorman
What an experienced grower watches for around here
In and around Glencoe, PFAS runs higher than the national average — 3 sites within ~10 miles of Glencoe. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.

Your land is one point inside Glencoe
Everything above resolves to Glencoe as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Volusia 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 Glencoe
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 Volusia 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 Glencoe
When does frost risk typically end in Glencoe?
The last hard freeze (28°F) in Glencoe typically lands around Jan 29, 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 Feb 19.
When is the first frost in Glencoe?
The first hard freeze (28°F) in Glencoe typically arrives around Dec 18, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 4, so the watching starts about Nov 18 — about 323 days after the spring freeze cleared.
How long is the growing season in Glencoe?
Measured between 28°F hard freezes, Glencoe sees about 323 frost-free days — roughly Jan 29 through Dec 18, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 19 to Dec 4, about 288 days.
Is the soil safe to grow vegetables in Glencoe?
The federal record around Glencoe is a meaningful one — 363 documented sites, mostly Underground Storage Tanks entries (209), the nearest Brownfields record about 0.4 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 Glencoe?
From about Nov 18 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 Dec 18 (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 Dec 18. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
