The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of getting a good idea when it's the best time to plant nemesia is to look at the USDA zone info for Middlesex.

Planting Calendar for Nemesia

Nemesia require warm weather which tells us that you must wait until it warms up after the last frost has passed before you can plant them.

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 really do well. You can get started a couple of weeks earlier by starting your nemesia indoors.
