Maryland planting calendar

When to plant peppers in Maryland — sow, transplant & harvest dates

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

Peppers planting timetable for Maryland

Stage	When in Maryland	Anchor
Start seeds indoors	mid-February (February 11)	9 weeks before the last frost (mid-April)
Transplant outside	late April (April 29)	14 days after the last frost (mid-April)
First harvest (estimate)	mid-July (July 18)	~80 days from transplant

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 Maryland's climate shifts the peppers dates

Maryland's last spring frost averages mid-April and first fall frost late October, which sets the whole planting clock. Maryland spans cool western mountains to a mild Chesapeake tidewater, giving a long, varied mid-Atlantic season. Wait for warm soil — peppers stall in cold ground even after the air warms, so don't rush them out.

Peppers need more heat than tomatoes — wait until soil temperatures hit 18 °C and nights stay above 13 °C. Short-season zones rely on transplants raised under lights for 8-10 weeks before going outside.

Frost-risk note

Don't plant before mid-April — even a light frost will kill seedlings overnight. In the western Appalachian panhandle near Oakland (zone 6a) the safe date runs a week or two later.

Regional variation within Maryland

the western Appalachian panhandle near Oakland (zone 6a) runs roughly 1-2 weeks behind the state average; the Chesapeake and Atlantic shoreline (zone 8a) can plant 1-2 weeks earlier.

Baltimore — USDA zone 8a
Annapolis — USDA zone 7b
Rockville — USDA zone 7b
Frederick — USDA zone 7a
Ocean City — USDA zone 8a

Frequently asked questions

When is the best time to plant peppers in Maryland?

In Maryland (mostly USDA zone 7b), sow peppers indoors around mid-February, transplant outdoors late April (after the last frost, mid-April), and harvest from mid-July. Peppers are frost-tender — a single light frost kills seedlings, so they only go outside once frost danger has fully passed and the soil is warm.

What USDA zone is Maryland?

Most of Maryland sits in USDA hardiness zone 7b, with the state spanning roughly 6a-8a from the western Appalachian panhandle near Oakland (zone 6a) to the Chesapeake and Atlantic shoreline (zone 8a). The last spring frost averages mid-April and the first fall frost late October.

Can you grow peppers in Maryland?

Yes. Maryland's dominant zone 7b supports peppers — the key is timing. Peppers are frost-tender — a single light frost kills seedlings, so they only go outside once frost danger has fully passed and the soil is warm.

Does the planting date change across Maryland?

the western Appalachian panhandle near Oakland (zone 6a) runs roughly 1-2 weeks behind the state average; the Chesapeake and Atlantic shoreline (zone 8a) can plant 1-2 weeks earlier.

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

Pair the post-frost slot with other warm-season crops — peppers, beans, squash, and cucumbers.
