Before planting it is a good idea to find your USDA Zone info to figure out 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.

In Vista you can estimate when you can plant echinacea by checking out the USDA zone info.

Planting Calendar for Echinacea

Frost tolerance for echinacea:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since echinacea 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 echinacea in Vista 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 echinacea and expect a good harvest is probably September. You probably don't want to wait any later than that or else your echinacea may not have a chance to really do well. You can get started a couple of weeks earlier by starting your echinacea indoors.

Last Frost Date

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

It's important to remember that USDA zone info for Vista is not always accurate and the actual date of last frost changes from year to year. Half of the time in Vista you get a frost after January 31 so always be ready to protect your echinacea if you have a surprise late frost.
