One of the best tools that you have as gardeners to help us determine your gardening schedule is the 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.

By referring to the USDA zone info for Victoria you should be able to determine when it's possible to plant arabis.

Planting Calendar for Arabis

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

Since arabis do well in cold you can plant them quite a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant arabis in Victoria 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 October. You probably don't want to wait any later than that or else your arabis may not have a chance to fully mature. Starting your arabis indoors is a great way to get them started a few weeks earlier.

Last Frost Date

Half of the time in Victoria it frosts late in the year after February 15 so just be sure to be ready to protect your arabis if you have one of those late frosts.
