One of the first steps you take when you are estimating your gardening schedule is find your 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 Washington you can figure out when you can plant gazania 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.

Gazania are barely cold tolerant which means that you can get them planted just a bit earlier than other frost tender plants.

The earliest that you can plant gazania in Washington 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 grow to maturity. You can get started a little bit earlier by starting your gazania indoors.

Last Frost Date

The average date of last frost is April 15 in Washington. In the coldest months of winter you should expect an average low temperature of -15°F.

Since the USDA zone info for Washington is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Washington it frosts late in the year after April 15 so make sure that you are ready to cover your gazania if you have a late frost.
