One of the first steps you take when you are estimating 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.

It's possible to estimate when to plant violets by checking out the USDA zone info for Zone 5b.

Planting Calendar for Violets

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

Violets do well in a little bit of cold which means that you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant violets in Zone 5b is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant violets and expect a good harvest is probably September. Any later than that and your violets may not have a chance to really do well. 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

The average date of last frost is April 15 in Zone 5b. You can expect an average low temperature of -15°F in the coldest months of winter.
