I bought some shallot bulbs last fall and planted them at the same time as my new garlic bulbs.

I harvested the shallots on July 3 because they had died down - good harvest, and they are wonderful! Now I'm wondering: should I replant some of them now for a fall harvest?

Since harvesting, I read that shallots "take 45 days," and most people plant them in the spring. Why not plant them in the summer for a September harvest?

I live in Connecticut, zone 5 - Thanks for any insights!
