When can I plant Doronicum in Zone 3a

Before planting it is a good idea to find our USDA Zone info to estimate our garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

One way of figuring out when to plant doronicum is to use the USDA zone info for Zone 3a.

The earliest that you can plant doronicum in Zone 3a 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 doronicum and expect a good harvest is probably August. Any later than that and your doronicum may not have a chance to really do well. If you are starting your doronicum indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

The average date of last frost is May 15 in Zone 3a. In the coldest months of winter we can expect an average low temperature of -40°F.

Keep in mind that our actual date of last frost is an average because it is based on the USDA zone info for Zone 3a and it is different every year. Half of the time in Zone 3a it frosts late in the year after May 15 so be sure to be ready to cover your doronicum in the event of one of those late frosts.
