When can I plant Carrots in Zone 1b

One of the first steps we take when we are getting a good idea our gardening schedule is find our USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

The USDA zone info for Zone 1b should be used to figure out when you can plant carrots.


Planting Calendar for Carrots

The earliest that you can plant carrots in Zone 1b 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 carrots and expect a good harvest is probably July. You probably don't want to wait any later than that or else your carrots may not have a chance to really do well. Starting your carrots indoors is a great way to get them started a few weeks earlier.

Last Frost Date

The average date of last frost is June 15 in Zone 1b. We should expect an average low temperature of -55°F in the coldest months of winter.

Since the USDA zone info for Zone 1b is just an average our actual date of last frost can change quite a bit from year to year. Half of the time in Zone 1b we get a frost after June 15 so be sure to be ready to protect your carrots in the event of a late frost.
