The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Kent you can figure out when you can plant violas by reviewing the USDA zone info.

Planting Calendar for Violas

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

Violas are very cold tolerant which means that you can get them planted much earlier than plants that are more sensitive to the cold.

The earliest that you can plant violas in Kent 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. You probably don't want to wait any later than that or else your violas may not have a chance to really do well. Starting your violas indoors is a great way to get them started a little bit earlier.

Last Frost Date

The average date of last frost is April 15 in Kent. It might get as low as -10°F during the coldest months of winter.

Since the USDA zone info for Kent is just an average the actual date of last frost can change quite a bit from year to year. Half of the time in Kent last frost occurs after April 15 so always be ready to protect your violas in the event of a late frost.
