One of the first steps you take when you are figuring out your gardening schedule is find your 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.

In Marathon you can estimate when you can plant arabis by using the USDA zone info.

Frost tolerance for arabis:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Since arabis are one of those plants that can tolerate quite a bit of cold weather you can plant them earlier in the year than other plants that might not handle the cold.

The earliest that you can plant arabis in Marathon 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 arabis and expect a good harvest is probably November. If you wait any later than that and your arabis may not have a chance to grow to maturity. Starting your arabis indoors is a great way to get them started a couple of weeks earlier.
