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 13a you can figure out when it's possible to plant arabis by reviewing the USDA zone info.

Planting Calendar for Arabis

Frost tolerance for arabis:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Since arabis do well in cold you can plant them much earlier in the year than other plants that might not handle the cold.

The earliest that you can plant arabis 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 arabis and expect a good harvest is probably November. You probably don't want to wait any later than that or else your arabis may not have a chance to grow to maturity. You can get started a little bit earlier by starting your arabis indoors.

Last Frost Date

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

It's important to remember that the actual date of last frost may not be accurate from year to year 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 arabis in the event of a surprise late frost.
