Start seeds indoors

Variety assumption: Illinois Extension notes summer savory can be harvested within two months of sowing, so one spring sowing carries the 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.
