One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Winters you can figure out when it's a good idea to plant cabbage by looking at the USDA zone info.

Planting Calendar for Cabbage

When to plant:	Up to 5 weeks before last frost.

Cabbage are one of those plants that can tolerate a little bit of cold weather which tells us that you can plant them a little bit earlier than other plants that might not handle the cold.

The earliest that you can plant cabbage in Winters 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 cabbage and expect a good harvest is probably October. You probably don't want to wait any later than that or else your cabbage may not have a chance to fully mature. If you are starting your cabbage indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date
