When can I plant Peonies in Zone 6a

One of the best tools that we have as gardeners to help us determine our gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

You will be able to determine when you can plant peonies by using the USDA zone info for Zone 6a.

The earliest that you can plant peonies in Zone 6a 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 grow to maturity. If you are starting your peonies indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 6a the average date of last frost happens on April 15. We can expect an average low temperature of -10°F in the coldest months of winter.

Since the USDA zone info for Zone 6a may not be accurate from year to year our actual date of last frost changes from year to year. Since half of the time in Zone 6a we get a frost after April 15 be ready to protect your peonies if we have a surprise late frost.
