One of the first steps you take when you are determining your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Berne you can determine when you can plant peonies by referring to the USDA zone info.

Planting Calendar for Peonies

Frost tolerance for peonies:	Tolerant of a very small amount of frost.
When to plant:	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 Berne 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 peonies and expect a good harvest is probably August. You probably don't want to wait any later than that or else your peonies may not have a chance to really do well. You can get started a couple of weeks earlier by starting your peonies indoors.

Last Frost Date

In Berne the average date of last frost happens on April 15. You can expect an average low temperature of -10°F in the coldest months of winter.

Since the USDA zone info for Berne is not always accurate the actual date of last frost changes from year to year. Half of the time in Berne you get a frost after April 15 so make sure that you are prepared to protect your peonies if you have a surprise late frost.
