Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. 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 the best time to plant nemesia is to check out the USDA zone info for Brookfield.

Planting Calendar for Nemesia

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

You should not plant nemesia until after the last frost because they are not cold tolerant.

The earliest that you can plant nemesia in Brookfield 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 fully mature. If you are starting your nemesia indoors then you might be able to get away with starting them a few weeks earlier.
