Start seeds indoors

Not calculated

Cilantro is tap-rooted and resents transplanting; the cited guide times direct sowing only.

Transplant outdoors

Not calculated

The cited extension guides do not time an outdoor transplanting window for this crop.

Fall planting

Not calculated

No source-backed fall planting rule exists for this crop in the registry, so no fall window is calculated.

Variety assumption: Leaf harvest begins about 40–50 days from sowing; bolts quickly in warm weather.

These windows describe typical years (1991–2020 climate normals), not this year's forecast. Freezes happen outside them — especially in frost pockets, valleys, and urban edges. Watch the forecast before committing tender plants.
