When to plant shallot in zone 3b

Method: Direct sow: Direct-sow outside. Shallot doesn't transplant well, or doesn't need the extra time indoors.

A shallot is an onion that decided to be several onions. Instead of swelling into one bulb it splits into a cluster of small ones, each with a milder, sweeter, more refined flavour than a cooking onion. It's the allium you want raw in a vinaigrette, where a raw onion would take over.
How shallot fits zone 3's season
Zone 3b's frost-free window runs about 98 days, from May 30 to September 5. Shallot needs about 108 days from sowing to first harvest.
