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 estimating when you can plant flowering tobacco is to use the USDA zone info for Charleston.

Planting Calendar for Flowering Tobacco

Frost tolerance for flowering tobacco:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

It's probably a bad idea to plant flowering tobacco until after all chance of frost has passed because they do not do well in cold weather.

The earliest that you can plant flowering tobacco in Charleston is April. However, you really should wait until May if you don't want to take any chances.

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

In Charleston the average date of last frost happens on April 15. In the coldest months of winter you can expect an average low temperature of -10°F.
