When can I plant Peonies in Zone 2a

The USDA Zone info is a great tool for gardeners to help us determine our gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

By using the USDA zone info for Zone 2a you should be able to figure out when it's the best time to plant peonies.


Planting Calendar for Peonies

Frost tolerance for peonies: Tolerant of a very small amount of frost.
When you should plant them: Up to 3 weeks before last frost.

Since peonies are barely cold tolerant you can plant them a bit earlier in the year than more sensitive plants.

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

The last month that you can plant peonies and expect a good harvest is probably August. If you wait any later than that and your peonies may not have a chance to really do well. Starting your peonies 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 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 is different every year. Half of the time in Zone 2a we get a frost after May 15 so make sure that you are prepared to protect your peonies if we have a late frost.
