Conditional — Some Areas
daikon radish (zones 2-11) has limited zone overlap with Arkansas (6b-8a). Only zones 6-8 in the state are suitable.
Your yard isn't the whole zone.
Arkansas spans zones 6b-8a, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score daikon radish against your land's actual soil, sun, and frost.

When to Plant Daikon Radish in Arkansas
The frost window
Across Arkansas, the last spring frost clears between Mar 15 and Apr 15, and the first fall frost lands between Oct 15 and Nov 10 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 183-day window you can count on — up to 240 days on a mild site in a kind year.
Frost tenderness
Daikon Radish is frost-tender — its listed minimum temperature is 50°F (USDA PLANTS Database) — so set plants out after the last frost has cleared your local site, not the state's earliest date.
Days to maturity vs. the window
At 60 days to maturity (USDA PLANTS Database), a planting right after last frost ripens with 123 days to spare even in Arkansas's tightest frost scenario — room for a later start or a second sowing.
Timing tuned to sub-state frost dates — Fulton County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Daikon Radish wants 50+ frost-free days; a typical Arkansas site sees ~220 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Growing degree days
Daikon Radish needs ~1000 GDD (base 50°F) to ripen. The state median runs ~4200 GDD (USDA NRCS county aggregates), so Arkansas's typical season clears that easily.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Daikon Radish likes near-neutral soil (pH 4.3-8.3). That's the common-ground band across Arkansas's silt loam and sandy loam — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Arkansas site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
Whether daikon radish is safe to eat from Arkansas soil is a block-by-block question, not a town-wide one — 21,012 documented contamination sites mean levels spike on some parcels and not the one next door, so only a test on your address settles it.

Daikon Radish in Arkansas — Quick Answer

What Else to Consider
Zone compatibility tells you about winter cold survival — but Arkansas growers also need to think about:
Hot, humid summers drive fungal and bacterial diseases
Morning base-watering, wide spacing, and resistant varieties keep disease manageable — your extension lists what holds up here.
Heavy clay soils in parts of the Ozarks
A raised bed gets you growing this season; compost worked in each fall opens the clay for the long run.
Severe spring storms and hail risk
Keep row cover staged through storm season — five minutes of shelter can save a bed of seedlings from hail.
Growing daikon radish here specifically
Daikon Radish grows its edible root in the soil itself, so on any of Arkansas's 21,012 documented contamination sites it can carry up lead you'd then eat.
Keep daikon radish in raised beds of screened clean soil and confirm your parcel's lead level before the first crop. How to handle it →
Timing shifts within Arkansas
Arkansas isn't one climate. In Fulton County, the last hard freeze (28°F) holds until about Mar 1 — roughly 19 days later than the recorded state median — so plant daikon radish to your county's window, not the statewide date.
County last-freeze dates: NOAA/PRISM Climate Normals 1991-2020, 28°F threshold (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Daikon Radish draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.

Common Questions About Growing Daikon Radish in Arkansas
When can I plant Daikon Radish in Arkansas?
Arkansas's last spring frost clears between Mar 15 and Apr 15, and the first fall frost lands between Oct 15 and Nov 10 (NOAA Climate Normals 1991-2020). Daikon Radish is frost-tender — its listed minimum temperature is 50°F (USDA PLANTS Database) — so wait until the last frost has cleared your specific site before planting out.
Can Daikon Radish mature before first frost in Arkansas?
Yes — Daikon Radish matures in 60 days (USDA PLANTS Database), and Arkansas's dependable frost-free window runs 183 days (NOAA Climate Normals 1991-2020), leaving 123 days of margin. Plant just after last frost and it ripens ahead of the first fall frost.
What hardiness zone is Daikon Radish grown in across Arkansas?
Arkansas spans USDA hardiness zones 6b-8a (USDA ARS PHZM 2023). Daikon Radish carries a range of zones 2-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Arkansas site have?
A typical Arkansas site sees ~220 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Daikon Radish needs 50+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Fulton, the freeze-free season runs shorter than the state average, so verify your own county's window.
How should I amend the soil for Daikon Radish in Arkansas?
Daikon Radish prefers pH 4.3-8.3 and well (dry spells) drainage (USDA PLANTS Database). That sits in the common-ground band across Arkansas soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
