When can I plant Aurinia in Zone 5a

The USDA Zone info is a great tool for gardeners to help us estimate our gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

The first chance to plant aurinia in Zone 5a can be determined by looking at the USDA zone info.

The earliest that you can plant aurinia 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 aurinia and expect a good harvest is probably September. You probably don't want to wait any later than that or else your aurinia may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your aurinia indoors.

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.

Just be sure to remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 5a and it changes from year to year. Half of the time in Zone 5a there is a last frost after April 15 so just be sure to be ready to protect your aurinia if we have a surprise late frost.
