When can I plant Kale in Zone 2a

One of the best tools that we have as gardeners to help us estimate our gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

In Zone 2a you can determine when it's possible to plant kale by reviewing the USDA zone info.


Planting Calendar for Kale

Frost tolerance for kale: Tolerant of some frost.
When you should plant them: Up to 5 weeks before last frost.

Kale can survive in moderate cold which tells us that you can plant them just a bit earlier in the year than more sensitive plants.

The earliest that you can plant kale in Zone 2a is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant kale and expect a good harvest is probably August. Any later than that and your kale may not have a chance to really do well. If you are starting your kale indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

On average the last frost is on May 15 in Zone 2a. We can expect an average low temperature of -50°F in the coldest months of winter.

Since the USDA zone info for Zone 2a is not always accurate our actual date of last frost will vary from year to year. Since half of the time in Zone 2a last frost occurs after May 15 be ready to cover your kale in the event of one of those late frosts.
