Zone 6 in October
October in Zone 6: A Longer Fall Window Than the Colder Zones Get
Seven crops are still plantable here, more than one zone north allows
Zone 6's October holds a wider planting list than a colder zone gets this late, garlic, shallot, fall onions, fava bean, chervil, and mache among them, all made possible by a first frost that typically waits until around October 15. That extra 10 days compared with a colder zone is enough to root a full round of alliums properly rather than rushing the last of them in before the ground locks up.
The deadline is still real, just later
Real as that extra time is, it runs out fast once the first hard freeze hits, since alliums and fava bean both need at least 2 to 3 weeks of workable soil to establish roots before winter dormancy sets in. Treat mid-October as the practical cutoff even though the average frost date sits a bit later, since a below-average year can bring a hard freeze 7 to 10 days early and catch a late planting with no root system to show for it.
What's still in the ground needs to come out before real cold
Winter squash and sweet potatoes should both be dug before nighttime temperatures dip toward freezing, since cold exposure shortens how long either one keeps in storage even without visible damage. Sweet potatoes want a curing period of 4 to 7 days at 85 degrees and 90 to 95 percent humidity to heal digging nicks and convert starches to sugar, a step that also thickens the skin enough to survive months in storage instead of weeks. Handle both crops gently at harvest, since a bruised squash or a nicked sweet potato rots from that exact spot within days, well before the rest of the crop shows any sign of trouble.
