The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Humboldt you can estimate 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 means that you can plant them slightly earlier than other frost tender plants.

The earliest that you can plant gazania in Humboldt is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant gazania and expect a good harvest is probably August. You probably don't want to wait any later than that or else your gazania may not have a chance to really do well. You can get started a little bit earlier by starting your gazania indoors.
