One of the first steps you take when you are figuring out 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.

A common way of figuring out when it's the best time to plant pansies is to consult the USDA zone info for Stoughton.

Planting Calendar for Pansies

Frost tolerance for pansies:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Since pansies are very cold tolerant you can plant them a lot earlier in the year than other frost tender plants.

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