Start seeds indoors

Not calculated

The cited extension guides do not time an indoor seed-starting window for this crop.

Direct-sow outdoors

Not calculated

Garden strawberries are planted as crowns/plants, not seed.

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: June-bearing beds fruit the year AFTER planting (blossoms are usually removed the first season).

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.

"Bare root dormant plants are transplanted in early spring. Since the plants are dormant, there is no need to wait until after the risk of spring frost has passed."
