One of the first steps you take when you are making a decision about your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The USDA zone info for Zone 10b should be looked at to estimate when it's possible to plant violets.

Planting Calendar for Violets

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

You can plant violets a little earlier in the year because they do well in moderate cold.

The earliest that you can plant violets 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 violets and expect a good harvest is probably October. Any later than that and your violets may not have a chance to really do well. Starting your violets 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. In the coldest months of winter you should expect an average low temperature of 35°F.

It's important to remember 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 there is a last frost after January 31 so make sure that you are prepared to protect your violets if you have one of those late frosts.
