Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

It's possible to figure out when you can plant artemesia by reviewing the USDA zone info for Dover.

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.

Since artemesia are barely cold tolerant you can plant them a bit earlier in the year than more sensitive plants.

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. If you are starting your artemesia indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

In Dover the average date of last frost happens on April 15. In the coldest months of winter you can expect an average low temperature of -15°F.

Since the USDA zone info for Dover is not always accurate the actual date of last frost is different every year. Half of the time in Dover there is a last frost after April 15 so make sure that you are prepared to cover your artemesia in the event of a surprise late frost.
