Kissimmee, Florida, sits in USDA hardiness zone 10a — a zone band wide enough that plant choice, not possibility, is the interesting question.
On paper, mango, tomato, orange, and sweet potato all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Kissimmee, 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 Kissimmee 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 Kissimmee
Each reading below is measured for Kissimmee itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsKissimmee runs about 323 days between hard freezes (read from Osceola County, the closest normal to Kissimmee) — 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
MeasuredKissimmee 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.

The kind of country Kissimmee is in
Kissimmee sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Kissimmee's own centroid rather than borrowed from Osceola County.
What Grows in Kissimmee
Plants matched to Kissimmee'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 Kissimmee?
For most of the year, no — what changes is which crops still fit the days remaining. 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 25 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 14 — 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.

- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •TRI facilities report what they release. Check the wind — downwind beds catch more of it.

Your land is one point inside Kissimmee
Everything above resolves to Kissimmee as a whole — one PHZM band, read across 14K acres, with hard-freeze dates borrowed from Osceola 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 Kissimmee
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 Osceola 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 Kissimmee
When does frost risk typically end in Kissimmee?
The last hard freeze (28°F) in Kissimmee typically lands around Jan 25, 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 15.
When is the first frost in Kissimmee?
The first hard freeze (28°F) in Kissimmee typically arrives around Dec 14, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 30, so the watching starts about Nov 14 — about 323 days after the spring freeze cleared.
How long is the growing season in Kissimmee?
Measured between 28°F hard freezes, Kissimmee sees about 323 frost-free days — roughly Jan 25 through Dec 14, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 15 to Nov 30, about 288 days.
Is the soil safe to grow vegetables in Kissimmee?
The federal record around Kissimmee is a meaningful one — 1,027 documented sites, mostly Underground Storage Tanks entries (501), the nearest Underground Storage Tanks record under a tenth of a mile 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 Kissimmee?
From about Nov 14 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 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 Dec 14. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
