One way of figuring out when it's a good idea to plant nemesia is to look at the USDA zone info for Stockton.

Planting Calendar for Nemesia

Since nemesia are not cold tolerant it is important to wait until after all chance of frost has passed before you can plant them.

The earliest that you can plant nemesia in Stockton is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant nemesia and expect a good harvest is probably September. If you wait any later than that and your nemesia may not have a chance to really do well. If you are starting your nemesia indoors then you might be able to get away with starting them a little bit earlier.
