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.

In Trussville you can determine when to plant achimenes by looking at the USDA zone info.

Since achimenes are not cold tolerant it is important to wait until after the last frost before you can plant them.

The last month that you can plant achimenes and expect a good harvest is probably August. If you wait any later than that and your achimenes may not have a chance to really do well. If you are starting your achimenes indoors then you might be able to get away with starting them a few weeks earlier.
