When to plant dill in Arkansas — sow, transplant & harvest dates

Arkansas is mostly USDA zone 7b (range 6b-8a). Dates below are derived from dill's frost tolerance and Arkansas's frost window — not generic national averages.

Dill planting timetable for Arkansas

Stage	When in Arkansas	Anchor
Direct-sow outside	mid-March (March 15)	21 days before the last frost (early April)
First harvest (estimate)	mid-May (May 14)	~60 days from direct sow

Dates are state-wide averages for the dominant zone. Local microclimates — elevation, urban heat, coastal moderation — can shift the window by 1-2 weeks. Use the frost-date calculator for a date tuned to your town.

Why Arkansas's climate shifts the dill dates

Arkansas's last spring frost averages early April and first fall frost late October, which sets the whole planting clock. Arkansas has a warm, humid, long season with mild winters. The Ozarks run a half zone cooler than the southern lowlands. Sow early — dill bolt once daytime temperatures hold above 24 °C, so the earlier they go in, the longer the harvest.

Dill develops a taproot early and transplants very poorly, so always direct-sow into its permanent spot 2-4 weeks before the last spring frost once the soil reaches at least 10 °C. It is hardy to light frosts and germinates in as little as 7 days in warm soil. Like cilantro, dill bolts quickly when temperatures climb above 27 °C (80 °F); successive small sowings every 2-3 weeks extend the leafy harvest, and a late sowing allowed to go to seed provides dill seed for pickling.

Frost-risk note

Don't plant before early April — a hard freeze can still set young plants back. In the Ozark and Ouachita highlands (zone 6b) the safe date runs a week or two later.

Regional variation within Arkansas

the Ozark and Ouachita highlands (zone 6b) runs roughly 1-2 weeks behind the state average; the southern and Delta lowlands near Little Rock (zone 8a) can plant 1-2 weeks earlier.

Little Rock — USDA zone 8a
Fayetteville — USDA zone 7a
Fort Smith — USDA zone 7b
Jonesboro — USDA zone 7b

Frequently asked questions

When is the best time to plant dill in Arkansas?

In Arkansas (mostly USDA zone 7b), direct-sow dill mid-March (before the last frost, early April), and harvest from mid-May. Dill are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

What USDA zone is Arkansas?

Most of Arkansas sits in USDA hardiness zone 7b, with the state spanning roughly 6b-8a from the Ozark and Ouachita highlands (zone 6b) to the southern and Delta lowlands near Little Rock (zone 8a). The last spring frost averages early April and the first fall frost late October.

Can you grow dill in Arkansas?

Yes. Arkansas's dominant zone 7b supports dill — the key is timing. Dill are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

Does the planting date change across Arkansas?

the Ozark and Ouachita highlands (zone 6b) runs roughly 1-2 weeks behind the state average; the southern and Delta lowlands near Little Rock (zone 8a) can plant 1-2 weeks earlier.

What else can I plant in Arkansas around the same time?

The same early window suits peas, lettuce, spinach, and onion sets.
