Maryland planting calendar

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

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

Chives planting timetable for Maryland

Stage	When in Maryland	Anchor
Start seeds indoors	early March (March 4)	6 weeks before the last frost (mid-April)
Transplant outside	early April (April 1)	14 days before the last frost (mid-April)
First harvest (estimate)	late May (May 31)	~60 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 chives 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 — chives stall in cold ground even after the air warms, so don't rush them out.

Start seeds indoors 6–8 weeks before the last spring frost; germination takes 7–14 days at 18–21 °C (65–70 °F), though seeds will germinate across a broad range of 15–35 °C (60–95 °F). As a cold-hardy perennial (zones 3–9), transplants can go out 1–2 weeks before the last frost once soil is workable — or direct-sow as soon as the ground can be worked in early spring. Begin snipping leaves about 30 days after transplanting (or ~60 days from seed) once plants reach 15 cm (6 in) tall; divide clumps every 3–4 years to maintain productivity.

Frost-risk note

Don't plant before mid-April — a hard freeze can still set young plants back. 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 chives in Maryland?

In Maryland (mostly USDA zone 7b), sow chives indoors around early March, transplant outdoors early April (before the last frost, mid-April), and harvest from late May. Chives 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 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 chives in Maryland?

Yes. Maryland's dominant zone 7b supports chives — the key is timing. Chives 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 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.
