One of the first steps you take when you are determining your gardening schedule is find your 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 12b you can determine when it's possible to plant hosta by using the USDA zone info.

Planting Calendar for Hosta

Frost tolerance for hosta:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

You can plant hosta a little earlier in the year because they are one of those plants that can tolerate a little bit of cold weather.

The earliest that you can plant hosta in Zone 12b 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 hosta and expect a good harvest is probably November. You probably don't want to wait any later than that or else your hosta may not have a chance to really do well. Starting your hosta indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 12b it never frosts. In the coldest months of winter you should expect an average low temperature of 55°F.

Just be sure to remember that the actual date of last frost is just an average because it is based on the USDA zone info for Zone 12b and it will vary from year to year. Since it never frosts in Zone 12b you do not have to be ready to protect your hosta if you have a late frost.
