One of the best tools that you have as gardeners to help us figure out 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.

In San Rafael you can determine when it's possible to plant gazania by reviewing the USDA zone info.

Planting Calendar for Gazania

Frost tolerance for gazania:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Gazania are barely cold tolerant which tells us that you can start planting them slightly earlier than other frost tender plants.

The earliest that you can plant gazania in San Rafael 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 gazania and expect a good harvest is probably September. You probably don't want to wait any later than that or else your gazania may not have a chance to grow to maturity. If you are starting your gazania indoors then you might be able to get away with starting them a few weeks earlier.
