When can I plant Chives in Zone 1a

You should be able to estimate when it's the best time to plant chives by referring to the USDA zone info for Zone 1a.

The earliest that you can plant chives in Zone 1a is May. However, you really should wait until June if you don't want to take any chances.

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

Last Frost Date

On average the last frost is on June 15 in Zone 1a. It might get as low as -60°F during the coldest months of winter.

Remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 1a and it is different every year. Since half of the time in Zone 1a we get surprised by a frost after June 15 be ready to cover your chives if we have a surprise late frost.
