One of the best tools that you have as gardeners to help us figure out 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.

In Minot you can estimate when it's the best time to plant impatiens by looking at the USDA zone info.

It's probably a bad idea to plant impatiens until after the last frost when the weather gets warmer because they are not cold tolerant.

The earliest that you can plant impatiens in Minot is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant impatiens and expect a good harvest is probably August. Any later than that and your impatiens may not have a chance to fully mature. Starting your impatiens indoors is a great way to get them started a couple of weeks earlier.
