When can I plant Aurinia in Zone 6a

The USDA Zone info is a great tool for gardeners to help us figure out 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.

A way of determining when it's the best time to plant aurinia is to use the USDA zone info for Zone 6a.

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Zone 6a. We can expect an average low temperature of -10°F in the coldest months of winter.

Remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 6a and it will vary from year to year. Since half of the time in Zone 6a we get a frost after April 15 be ready to cover your aurinia if we have one of those late frosts.
