Shallots can survive in very little cold which tells us that you can plant them just a tiny bit earlier in the year than other plants that might not handle the cold.

The last month that you can plant shallots and expect a good harvest is probably September. You probably don't want to wait any later than that or else your shallots may not have a chance to really do well. Starting your shallots indoors is a great way to get them started a couple of weeks earlier.
