The first opportunity to plant parsley in Zone 10b should be estimated by looking at the USDA zone info.

Parsley tend to make it in mild cold which tells us that you can plant them just a bit earlier in the year than more sensitive plants.

The earliest that you can plant parsley in Zone 10b 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 parsley and expect a good harvest is probably October. Any later than that and your parsley may not have a chance to really do well. Starting your parsley indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

In Zone 10b the average date of last frost happens on January 31. It might get as low as 35°F during the coldest months of winter.

Keep in mind that the actual date of last frost is an average because it is based on the USDA zone info for Zone 10b and it can change quite a bit from year to year. Half of the time in Zone 10b it frosts late in the year after January 31 so make sure that you are prepared to cover your parsley in the event of a late frost.
