Before planting it is a good idea to find your USDA Zone info to figure out 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 getting a good idea when it's possible to plant cerastium is to refer to the USDA zone info for Norwalk.

Planting Calendar for Cerastium

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

Cerastium tend to make it in mild cold which tells us that you can plant them a little earlier in the year than other frost tender plants.

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

The last month that you can plant cerastium and expect a good harvest is probably October. You probably don't want to wait any later than that or else your cerastium may not have a chance to grow to maturity. Starting your cerastium indoors is a great way to get them started a few weeks earlier.

Last Frost Date

In Norwalk the average date of last frost happens on January 31. In the coldest months of winter you should expect an average low temperature of 35°F.

Just be sure to remember that USDA zone info for Norwalk may not be accurate from year to year and the actual date of last frost is different every year. Since half of the time in Norwalk last frost occurs after January 31 be ready to protect your cerastium if you have one of those late frosts.
