When can I plant Violas in Zone 2a

Before planting it is a good idea to find our USDA Zone info to estimate our garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

The first chance to plant violas in Zone 2a can be estimated by looking at the USDA zone info.


Planting Calendar for Violas

Frost tolerance for violas: Very tolerant of frost.
When you should plant them: Up to 7 weeks before last frost.

Violas do well in pretty solid cold which tells us that you can plant them quite a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant violas in Zone 2a is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant violas and expect a good harvest is probably August. You probably don't want to wait any later than that or else your violas may not have a chance to grow to maturity. If you are starting your violas indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 2a the average date of last frost happens on May 15. We can expect an average low temperature of -50°F in the coldest months of winter.

Since the USDA zone info for Zone 2a is not always accurate our actual date of last frost will vary from year to year. Half of the time in Zone 2a we get a frost after May 15 so be sure to be ready to protect your violas if we have a late frost.
