One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A common way of determining when it's a good idea to plant violas is to look at the USDA zone info for Lincolnshire.

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

Violas can survive in quite a bit of cold which means that you can plant them much earlier in the year than more sensitive plants.

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 grow to maturity. Starting your violas indoors is a great way to get them started a little bit earlier.
