One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of determining when it's a good idea to plant achimenes is to examine the USDA zone info for Fremont.

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