When can I plant Echinacea in Zone 1a

The USDA Zone info is a great tool for gardeners to help us estimate our gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

In Zone 1a you can figure out when you can plant echinacea by referring to the USDA zone info.

The earliest that you can plant echinacea in Zone 1a is June. However, you really should wait until July if you don't want to take any chances.

The last month that you can plant echinacea and expect a good harvest is probably July. If you wait any later than that and your echinacea may not have a chance to fully mature. Starting your echinacea indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 1a the average date of last frost happens on June 15. We should expect an average low temperature of -60°F in the coldest months of winter.

Just be sure to remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 1a and it can change quite a bit from year to year. Since half of the time in Zone 1a last frost occurs after June 15 be ready to protect your echinacea if we have a late frost.
