When can I plant Red Hot Pokers in Zone 1a

One of the best tools that we have as gardeners to help us estimate our 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 our area.

In Zone 1a you can estimate when it's a good idea to plant red hot pokers by looking at the USDA zone info.

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

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

Last Frost Date

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

Since the USDA zone info for Zone 1a may not be accurate from year to year our actual date of last frost changes from year to year. Half of the time in Zone 1a we get surprised by a frost after June 15 so just be sure to be ready to cover your red hot pokers if we have one of those late frosts.
