Utah State University Extension says garden cress "does not tolerate frost so plant near the frost free date", and Arkansas Extension's culture line reads "seed shallow depth after danger of frost"; both open at the last spring frost, and this later interval supersedes Arkansas' looser "as soon as the ground can be worked" sentence, giving last spring frost to plus 14 days.

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: Offsets are for garden cress (Lepidium sativum), a 10–40 day cutting green; watercress and upland cress are different species with different requirements and are not covered by this entry.

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.
