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.

A way of making a decision about when to plant feverfew is to consult the USDA zone info for Zone 2b.

Planting Calendar for Feverfew

Frost tolerance for feverfew:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Feverfew are moderately cold tolerant which means that you can plant them a little bit earlier than plants that are more sensitive to the cold.

The earliest that you can plant feverfew in Zone 2b is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant feverfew and expect a good harvest is probably August. You probably don't want to wait any later than that or else your feverfew may not have a chance to really do well. If you are starting your feverfew indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 2b the average date of last frost happens on May 15. You should expect an average low temperature of -45°F in the coldest months of winter.

Keep in mind that the actual date of last frost is just an average because it is based on the USDA zone info for Zone 2b and it changes from year to year. Half of the time in Zone 2b it frosts late in the year after May 15 so make sure that you are prepared to cover your feverfew if you have one of those late frosts.
