Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. 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 making a decision about when it's possible to plant aubretia is to consult the USDA zone info for Ceres.

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

Last Frost Date

On average the last frost when the weather gets warmer is on February 15 in Ceres. You can expect an average low temperature of 25°F in the coldest months of winter.

Since the USDA zone info for Ceres is not always accurate the actual date of last frost is different every year. Since half of the time in Ceres last frost occurs after February 15 be ready to cover your aubretia in the event of one of those late frosts.
