One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Zone 12b you can figure out when it's a good idea to plant chervil by reviewing the USDA zone info.

Planting Calendar for Chervil

Frost tolerance for chervil:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Chervil are barely cold tolerant which means that you can plant them slightly earlier than other frost tender plants.

The last month that you can plant chervil and expect a good harvest is probably November. You probably don't want to wait any later than that or else your chervil may not have a chance to really do well. You can get started a few weeks earlier by starting your chervil indoors.

Last Frost Date

It's important to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 12b and it is different every year. Since it never frosts in Zone 12b you do not have to be ready to cover your chervil if you have one of those late frosts.
