Fall planting

Jul 31 – Aug 14

University of Arkansas Cooperative Extension fact sheet FSA6094 says to "Plant the seed in deep, well-prepared fertile soil in late spring or summer (about 100 days before freezing weather)," and the parenthetical — the only frost-anchored part of the instruction — encodes as a 14-day sowing span opening 100 days before the first freeze; no other extension source with a frost-relative salsify rule was found, so nothing required reconciling.

Start seeds indoors

Not calculated

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

Transplant outdoors

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

Direct-sow outdoors

The University of Arkansas fact sheet gives salsify's spring timing only as a season ("seed late winter or spring"), not as an offset from the last spring freeze, so no spring window is computed here.

Variety assumption: Assumes true salsify (Tragopogon porrifolius) such as Mammoth Sandwich Island at about 120 days; note the Arkansas fact sheet heads its section "Salsify – Tragopogon porrifolius or Scorzonera hispanica" and lists a black-rooted scorzonera cultivar alongside it, so this entry deliberately covers only Tragopogon and black salsify is left as a separate plant.

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.
