One of the best tools that you have as gardeners to help us estimate your 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 your area.

One way of making a decision about when to plant violets is to refer to the USDA zone info for Zone 13a.

Planting Calendar for Violets

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

Since violets are moderately cold tolerant you can plant them a little earlier in the year than other frost tender plants.

The earliest that you can plant violets 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 violets and expect a good harvest is probably November. You probably don't want to wait any later than that or else your violets may not have a chance to fully mature. If you are starting your violets indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

In Zone 13a it never frosts. You can expect an average low temperature of 60°F in the coldest months of winter.

Since the USDA zone info for Zone 13a is an average the actual date of last frost can change quite a bit from year to year. Since it never frosts in Zone 13a you do not have to be ready to cover your violets in the event of a late frost.
