One of the best tools that you have as gardeners to help us determine your gardening schedule is the 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 it's possible to plant nemesia is to use the USDA zone info for Jefferson City.

Since nemesia do not do well in cold weather you must wait until after the last frost has passed before you can plant them.

The earliest that you can plant nemesia in Jefferson City 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 nemesia and expect a good harvest is probably August. You probably don't want to wait any later than that or else your nemesia may not have a chance to grow to maturity. You can get started a little bit earlier by starting your nemesia indoors.
