The earliest that you can plant aurinia in Zone 3a is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant aurinia and expect a good harvest is probably August. Any later than that and your aurinia may not have a chance to really do well. Starting your aurinia indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is May 15 in Zone 3a. It might get as low as -40°F during the coldest months of winter.

Keep in mind that our actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Zone 3a and it will vary from year to year. Since half of the time in Zone 3a last frost occurs after May 15 be ready to protect your aurinia if we have a surprise late frost.
