When can I plant Digitalis in Zone 10a

Before planting it is a good idea to find our USDA Zone info to figure out our garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

A common way of estimating when you can plant digitalis is to look at the USDA zone info for Zone 10a.

Last Frost Date

On average the last frost has passed is on January 31 in Zone 10a. We can expect an average low temperature of 30°F in the coldest months of winter.

Just be sure to remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 10a and it can change quite a bit from year to year. Since half of the time in Zone 10a last frost occurs after January 31 be ready to protect your digitalis in the event of a late frost.
