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.

A common way of estimating when you can plant feverfew is to consult the USDA zone info for Louisville.

Feverfew are one of those plants that can tolerate a little bit of cold weather which means that you can start planting them earlier than plants that are more sensitive to the cold.

The earliest that you can plant feverfew in Louisville 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 feverfew and expect a good harvest is probably September. You probably don't want to wait any later than that or else your feverfew may not have a chance to really do well. Starting your feverfew indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Louisville the average date of last frost happens on April 15. It might get as low as -10°F during the coldest months of winter.

Keep in mind that the actual date of last frost is an average because it is based on the USDA zone info for Louisville and it changes from year to year. Half of the time in Louisville there is a last frost after April 15 so just be sure to be ready to protect your feverfew if you have one of those late frosts.
