When can I plant Cucumbers in Zone 12a

One of the best tools that we have as gardeners to help us figure out 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.

A way of figuring out when it's the best time to plant cucumbers is to consult the USDA zone info for Zone 12a.

The earliest that you can plant cucumbers in Zone 12a 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 cucumbers and expect a good harvest is probably November. You probably don't want to wait any later than that or else your cucumbers may not have a chance to fully mature. You can get started a little bit earlier by starting your cucumbers indoors.

Last Frost Date

Since the USDA zone info for Zone 12a may not be accurate from year to year our actual date of last frost changes from year to year. Since it never frosts in Zone 12a you do not have to be ready to cover your cucumbers if we have a surprise late frost.
