Direct-sow outdoors
Apr 20 – May 4Utah State Extension ties the peanut sowing trigger directly to the frost anchor — sow when soil temperatures are above 65°F, which it says is usually around the last frost — so the point rule opens the window at the last-frost date and runs 14 days. No source in this set offered an earlier-starting alternative to reconcile against. Anchored to the median last spring freeze (Apr 20). Utah State University Extension
Start seeds indoors
Not calculatedThe cited extension guides do not time an indoor seed-starting window for this crop.
Transplant outdoors
Not calculatedThe cited extension guides do not time an outdoor transplanting window for this crop.
Fall planting
Not calculatedNo source-backed fall planting rule exists for this crop in the registry, so no fall window is calculated.
Variety assumption: Assumes a shorter-season Spanish or Valencia type sown in place; Arkansas Extension notes peanuts need a minimum of 120 frost-free days, so the crop is only viable where the anchor-to-anchor season exceeds that.
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.
