One of the best tools that you have as gardeners to help us figure out your 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 your area.

The USDA zone info for Petal can be reviewed to estimate when it's possible to plant armeria.

Planting Calendar for Armeria

Frost tolerance for armeria:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Armeria do well in quite a bit of cold which means that you can plant them earlier in the year than other frost tender plants.

The earliest that you can plant armeria in Petal 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 armeria and expect a good harvest is probably September. Any later than that and your armeria may not have a chance to really do well. Starting your armeria indoors is a great way to get them started a couple of weeks earlier.

In Petal 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 Petal is not always accurate the actual date of last frost changes from year to year. Half of the time in Petal last frost occurs after March 15 so always be ready to cover your armeria in the event of one of those late frosts.
