One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of making a decision about when to plant trachelium is to use the USDA zone info for Sedona.

The last month that you can plant trachelium and expect a good harvest is probably August. You probably don't want to wait any later than that or else your trachelium may not have a chance to fully mature. If you are starting your trachelium indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date
