One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Zone 13a you can estimate when to plant geranium by using the USDA zone info.

Planting Calendar for Geranium

Frost tolerance for geranium:	Not tolerant of frost.
When to plant:	After the last frost when the weather gets warmer.

You really shouldn't plant geranium until after the last frost because they are not cold tolerant.

The earliest that you can plant geranium 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 geranium and expect a good harvest is probably November. You probably don't want to wait any later than that or else your geranium may not have a chance to fully mature. If you are starting your geranium indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

In Zone 13a it never frosts. In the coldest months of winter you can expect an average low temperature of 60°F.

Since the USDA zone info for Zone 13a is not always accurate the actual date of last frost will vary from year to year. Since it never frosts in Zone 13a you do not have to be ready to cover your geranium in the event of a surprise late frost.
