Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A common way of estimating when you can plant nemesia is to look at the USDA zone info for Zone 8b.

Planting Calendar for Nemesia

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

It's a bad idea to plant nemesia until after the last frost when the weather gets warmer because they require warm weather.

The earliest that you can plant nemesia in Zone 8b 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. Any later than that and your nemesia may not have a chance to grow to maturity. If you are starting your nemesia indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

The average date of last frost is March 15 in Zone 8b. It might get as low as 15°F during the coldest months of winter.

Always keep in mind that USDA zone info for Zone 8b is not always accurate and the actual date of last frost can change quite a bit from year to year. Half of the time in Zone 8b last frost occurs after March 15 so make sure that you are ready to protect your nemesia in the event of a late frost.
