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.

In Audubon you can determine when to plant cauliflower by referring to the USDA zone info.

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

Since cauliflower are one of those plants that can tolerate a little bit of cold weather you can plant them a little bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant cauliflower in Audubon 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 cauliflower and expect a good harvest is probably September. If you wait any later than that and your cauliflower may not have a chance to really do well. If you are starting your cauliflower indoors then you might be able to get away with starting them a few weeks earlier.
