When can I plant Fanflower in Zone 1a

One of the first steps we take when we are figuring out our gardening schedule is find our USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

One way of estimating when you can plant fanflower is to look at the USDA zone info for Zone 1a.

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

Last Frost Date

On average all chance of frost has passed is on June 15 in Zone 1a. We should expect an average low temperature of -60°F in the coldest months of winter.

Since the USDA zone info for Zone 1a is not always accurate our actual date of last frost will vary from year to year. Since half of the time in Zone 1a we get surprised by a frost after June 15 be ready to cover your fanflower if we have one of those late frosts.
