Before planting it is a good idea to find your USDA Zone info to estimate 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 you can plant cerastium is to consult the USDA zone info for Andalusia.

Planting Calendar for Cerastium

Frost tolerance for cerastium:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

You can plant cerastium a bit earlier in the year because they are moderately cold tolerant.

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

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

Last Frost Date

On average the last frost when the weather gets warmer is on March 15 in Andalusia. In the coldest months of winter you should expect an average low temperature of 10°F.

Since the USDA zone info for Andalusia is not always accurate the actual date of last frost is different every year. Since half of the time in Andalusia last frost occurs after March 15 be ready to cover your cerastium if you have a surprise late frost.
