One of the first steps you take when you are determining your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The first chance to plant lunaria in Coronado should be determined by reviewing the USDA zone info.

Planting Calendar for Lunaria

Frost tolerance for lunaria:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since lunaria do well in moderate cold you can plant them a little bit earlier in the year than more sensitive plants.

The earliest that you can plant lunaria in Coronado is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant lunaria and expect a good harvest is probably October. You probably don't want to wait any later than that or else your lunaria may not have a chance to grow to maturity. Starting your lunaria indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

In Coronado the average date of last frost happens on January 31. In the coldest months of winter you should expect an average low temperature of 35°F.

Since the USDA zone info for Coronado is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Coronado you get a frost after January 31 so always be ready to protect your lunaria if you have a late frost.
