Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Norwich you can figure out when it's the best time to plant violas by referring to the USDA zone info.

When to plant:	Up to 7 weeks before last frost.

Since violas 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 violas in Norwich 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 violas and expect a good harvest is probably September. Any later than that and your violas may not have a chance to really do well. If you are starting your violas indoors then you might be able to get away with starting them a few weeks earlier.
