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 Zone 6a you can estimate when you can plant artemesia by using the USDA zone info.

Planting Calendar for Artemesia

Frost tolerance for artemesia:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Artemesia do ok in some cold which means that you can plant them slightly earlier in the year than other frost tender plants.

The earliest that you can plant artemesia 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 artemesia and expect a good harvest is probably August. Any later than that and your artemesia may not have a chance to grow to maturity. Starting your artemesia indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

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

Just be sure to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 6a and it can change quite a bit from year to year. Half of the time in Zone 6a you get a frost after April 15 so be sure to be ready to cover your artemesia if you have a late frost.
