When should I plant shallots? I live in Zone 5.

From sets?
Probably the middle of last month (October). About the time you would have
planted bulbs like tulips or daffodils.

There are new varieties that are started from seed. Start those indoors, or
in a greenhouse in January or February to set out in mid-April to early May.
