One of the first steps you take when you are determining your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of figuring out when to plant trachelium is to check out the USDA zone info for Zone 11a.

Planting Calendar for Trachelium

Frost tolerance for trachelium:	Not tolerant of frost.
When to plant:	After the last frost has passed.

Since trachelium do not do well in cold weather it's necessary to wait until after all chance of frost has passed before you can plant them.

The earliest that you can plant trachelium in Zone 11a is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant trachelium and expect a good harvest is probably November. If you wait any later than that and your trachelium may not have a chance to really do well. 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

In Zone 11a it never frosts. It might get as low as 40°F during the coldest months of winter.

Keep in mind that USDA zone info for Zone 11a is not always accurate and the actual date of last frost is different every year. Since it never frosts in Zone 11a you do not have to be ready to protect your trachelium if you have a late frost.
