One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Lebanon you can determine when it's a good idea to plant mimulus by looking at the USDA zone info.

The last month that you can plant mimulus and expect a good harvest is probably August. You probably don't want to wait any later than that or else your mimulus may not have a chance to really do well. You can get started a couple of weeks earlier by starting your mimulus indoors.
