One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

You can estimate when it's a good idea to plant fanflower in Zone 10a by referring to the USDA zone info.

Planting Calendar for Fanflower

Frost tolerance for fanflower:	Not tolerant of frost.
When to plant:	After the last frost when the weather gets warmer.

You really shouldn't plant fanflower until after the last frost when the weather gets warmer because they do not do well in cold weather.

The earliest that you can plant fanflower in Zone 10a 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 fanflower and expect a good harvest is probably September. You probably don't want to wait any later than that or else your fanflower may not have a chance to grow to maturity. Starting your fanflower indoors is a great way to get them started a few weeks earlier.

Last Frost Date

The average date of last frost is January 31 in Zone 10a. You can expect an average low temperature of 30°F in the coldest months of winter.

Just be sure to remember that the actual date of last frost is an average because it is based on the USDA zone info for Zone 10a and it is different every year. Half of the time in Zone 10a there is a last frost after January 31 so make sure that you are ready to cover your fanflower if you have one of those late frosts.
