USDA Zone 7 planting calendar
When to plant cilantro in USDA zone 7
Sowing, transplant, and harvest dates calibrated to zone 7's 200-day season (Virginia, North Carolina (mountains), Oklahoma, Tennessee).
Key dates for cilantro in zone 7
| Stage | When | Anchor |
|---|---|---|
| Direct sow outdoors | late March (March 25) | 21 days before last frost (mid-April) |
| First harvest (estimate) | mid-May (May 14) | ~50 days from sow |
Dates are zone-wide averages. Local microclimates (south-facing slopes, urban heat, lakeside warmth, elevation) can shift the planting window by 1-2 weeks within the same zone.
Why this timing works for zone 7
Zone 7 has average annual minimum temperatures of 0 to 10°F and a 200-day frost-free window from mid-April to late October / early November. Cilantro are hardy enough to handle light frost — and in fact prefer cool weather. They bolt or turn bitter once daytime temperatures consistently climb above 24 °C, which is why earlier is better in zone 7.
Cilantro resents transplanting and should always be direct-sown; its taproot breaks easily and transplant shock triggers immediate bolting. Sow 2-3 weeks before the last spring frost when soil is 10-29 °C, then succession-sow every 2-3 weeks through early summer, stopping once daytime temperatures consistently exceed 27 °C (80 °F) — above that threshold the plant bolts within days and goes straight to seed. In zones 8-11 cilantro is best grown as a fall and winter crop.
Quick-grow guide
- Sun: Full sun to partial shade — 4-6 hours direct.
- Soil temperature for germination: 10-29 °C (50-85 °F).
- Spacing: 4-6 inches (10-15 cm) between plants.
- Days to harvest from direct sow: ~50 days.
- Plant in cool weather and provide afternoon shade once temperatures climb above 24 °C.
Common mistakes — zone 7 × cilantro
- Planting before last frost: zone 7's last frost averages mid-April, and even a light frost will kill cilantro seedlings overnight.
- Skipping hardening off: even healthy indoor transplants need 7-10 days of progressive outdoor exposure before going in the ground.

Frost-date averages from NOAA Climate Data Online within each USDA hardiness zone. Hardiness zone boundaries from the USDA Plant Hardiness Zone Map (2023). Crop timing offsets calibrated against US Cooperative Extension Service publications (UNL, UMN, NC State, Texas A&M, UF/IFAS) and cross-checked against the RHS sowing calendar for en-GB readers.
