When can I plant Strawflowers in Zone 10a

One of the best tools that we have as gardeners to help us estimate our gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

In Zone 10a you can determine when it's the best time to plant strawflowers by checking out the USDA zone info.

The earliest that you can plant strawflowers 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 strawflowers and expect a good harvest is probably September. You probably don't want to wait any later than that or else your strawflowers may not have a chance to fully mature. Starting your strawflowers indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 10a the average date of last frost happens on January 31. We can expect an average low temperature of 30°F in the coldest months of winter.

It's important to remember that our 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 last frost occurs after January 31 so just be sure to be ready to protect your strawflowers if we have a late frost.
