The last month that you can plant aegopodium and expect a good harvest is probably August. Any later than that and your aegopodium may not have a chance to really do well. If you are starting your aegopodium indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

The average date of last frost is May 15 in Zone 4a. In the coldest months of winter we should expect an average low temperature of -30°F.

Always keep in mind that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 4a and it changes from year to year. Since half of the time in Zone 4a last frost occurs after May 15 be ready to protect your aegopodium if we have a late frost.
