When can I plant Trachelium in Zone 1a

One of the first steps we take when we are making a decision about 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.

In Zone 1a you can estimate when it's a good idea to plant trachelium by using the USDA zone info.

The earliest that you can plant trachelium 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 trachelium and expect a good harvest is probably July. Any later than that and your trachelium may not have a chance to grow to maturity. Starting your trachelium 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.

Just be sure to remember that our actual date of last frost is an average because it is based on the USDA zone info for Zone 1a and it changes from year to year. Half of the time in Zone 1a last frost occurs after June 15 so make sure that you are ready to cover your trachelium in the event of a late frost.
