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.

One way of making a decision about when to plant gazania is to use the USDA zone info for Chattanooga.

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 slightly earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant gazania in Chattanooga 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. If you wait any later than that and 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 little bit earlier.

Last Frost Date

The average date of last frost is April 15 in Chattanooga. It might get as low as 5°F during the coldest months of winter.

Remember that USDA zone info for Chattanooga is an average and the actual date of last frost can change quite a bit from year to year. Half of the time in Chattanooga there is a last frost after April 15 so be sure to be ready to protect your gazania if you have a surprise late frost.
