When can I plant Violets in Zone 4a

One of the first steps we take when we are making a decision about our gardening schedule is find our USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

In Zone 4a you can determine when you can plant violets by looking at the USDA zone info.

The earliest that you can plant violets in Zone 4a is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant violets and expect a good harvest is probably August. You probably don't want to wait any later than that or else your violets may not have a chance to grow to maturity. You can get started a little bit earlier by starting your violets indoors.

Last Frost Date

The average date of last frost is May 15 in Zone 4a. In the coldest months of winter we should expect an average low temperature of -30°F.

Since the USDA zone info for Zone 4a may not be accurate from year to year our actual date of last frost can change quite a bit from year to year. Half of the time in Zone 4a it frosts late in the year after May 15 so just be sure to be ready to protect your violets if we have one of those late frosts.
