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

A way of estimating when it's possible to plant peonies is to use the USDA zone info for Marana.

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.

Peonies do well in mild cold which tells us that you can plant them a bit earlier in the year than other frost tender plants.

The earliest that you can plant peonies in Marana is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant peonies and expect a good harvest is probably September. You probably don't want to wait any later than that or else your peonies may not have a chance to fully mature. Starting your peonies indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

In Marana the average date of last frost happens on February 15. You can expect an average low temperature of 20°F in the coldest months of winter.

It's important to remember that USDA zone info for Marana is not always accurate and the actual date of last frost changes from year to year. Half of the time in Marana last frost occurs after February 15 so always be ready to protect your peonies in the event of one of those late frosts.
