The earliest that you can plant sorrel in Zone 3b is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant sorrel and expect a good harvest is probably August. You probably don't want to wait any later than that or else your sorrel may not have a chance to fully mature. If you are starting your sorrel indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

On average the last frost has passed is on May 15 in Zone 3b. In the coldest months of winter we should expect an average low temperature of -35°F.

Since the USDA zone info for Zone 3b is not always accurate our actual date of last frost can change quite a bit from year to year. Since half of the time in Zone 3b last frost occurs after May 15 be ready to protect your sorrel if we have a surprise late frost.
