Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Dallas you can determine when it's possible to plant peonies by checking out 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 slightly earlier in the year than other frost tender plants.

The earliest that you can plant peonies in Dallas 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 fully mature. You can get started a few weeks earlier by starting your peonies indoors.

Last Frost Date

In Dallas the average date of last frost happens on March 15. You should expect an average low temperature of 15°F in the coldest months of winter.

Since the USDA zone info for Dallas may not be accurate from year to year the actual date of last frost is different every year. Half of the time in Dallas last frost occurs after March 15 so always be ready to protect your peonies in the event of one of those late frosts.
