Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

By referring to the USDA zone info for Zone 13a you will be able to determine when it's possible to plant radishes.

Planting Calendar for Radishes

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

You can plant radishes quite a bit earlier in the year because they are very cold tolerant.

The earliest that you can plant radishes 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 radishes and expect a good harvest is probably November. Any later than that and your radishes may not have a chance to grow to maturity. You can get started a little bit earlier by starting your radishes indoors.

Last Frost Date

It's important to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 13a and it is different every year. Since it never frosts in Zone 13a you do not have to be ready to cover your radishes if you have a late frost.
