When can I plant Arabis in Zone 2a

One of the first steps we take when we are estimating 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.

In Zone 2a you can estimate when it's possible to plant arabis by looking at the USDA zone info.

The earliest that you can plant arabis 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 arabis and expect a good harvest is probably August. Any later than that and your arabis may not have a chance to fully mature. If you are starting your arabis 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 2a. In the coldest months of winter we can expect an average low temperature of -50°F.

Just be sure to remember that USDA zone info for Zone 2a is not always accurate and our actual date of last frost will vary from year to year. Half of the time in Zone 2a there is a last frost after May 15 so just be sure to be ready to cover your arabis if we have a surprise late frost.
