When can I plant Calibrachoa in Zone 13a

One of the best tools that we have as gardeners to help us estimate our 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 our area.

It's a good idea to figure out when it's the best time to plant calibrachoa by using the USDA zone info for Zone 13a.

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

Last Frost Date

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

Just be sure to remember that our actual date of last frost is not always accurate 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 protect your calibrachoa if we have one of those late frosts.
