One of the best tools that you have as gardeners to help us determine 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 Apex you can estimate when to plant cauliflower by using the USDA zone info.

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

Since cauliflower are moderately cold tolerant you can plant them a little earlier in the year than other plants that might not handle the cold.

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 little bit earlier.
