When can I plant Carrots in Zone 5a

Before planting it is a good idea to find our USDA Zone info to figure out our garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

One way of determining when it's a good idea to plant carrots is to use the USDA zone info for Zone 5a.

The earliest that you can plant carrots in Zone 5a is February. However, you really should wait until March if you don't want to take any chances.

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

Last Frost Date

The average date of last frost is April 15 in Zone 5a. It might get as low as -20°F during the coldest months of winter.

Since the USDA zone info for Zone 5a is an average our actual date of last frost can change quite a bit from year to year. Since half of the time in Zone 5a there is a last frost after April 15 be ready to protect your carrots if we have a late frost.
