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 possible to plant lettuce is to refer to the USDA zone info for Zone 13a.

Planting Calendar for Lettuce

Frost tolerance for lettuce:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

You can plant lettuce a bit earlier in the year because they are one of those plants that can tolerate a little bit of cold weather.

The earliest that you can plant lettuce in Zone 13a is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant lettuce and expect a good harvest is probably November. Any later than that and your lettuce may not have a chance to really do well. If you are starting your lettuce indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 13a it never frosts. It might get as low as 60°F during the coldest months of winter.

Just be sure to remember that the actual date of last frost is just an average because it is based on the USDA zone info for Zone 13a and it can change quite a bit from year to year. Since it never frosts in Zone 13a you do not have to be ready to cover your lettuce if you have a late frost.
