You can determine when to plant achimenes in Ceres by referring to the USDA zone info.

Planting Calendar for Achimenes

Frost tolerance for achimenes:	Not tolerant of frost.
When to plant:	After the last frost.

You really shouldn't plant achimenes until after the last frost when the weather gets warmer because they do not do well in cold weather.

The earliest that you can plant achimenes in Ceres is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant achimenes and expect a good harvest is probably September. If you wait any later than that and your achimenes may not have a chance to fully mature. If you are starting your achimenes indoors then you might be able to get away with starting them a little bit earlier.
