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.

The earliest that you can plant gazania in Northfield should be determined by using 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.

Since gazania are barely cold tolerant you can plant them just a tiny bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant gazania in Northfield is April. However, you really should wait until May 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 fully mature. If you are starting your gazania indoors then you might be able to get away with starting them a few weeks earlier.
