One of the best tools that you have as gardeners to help us estimate your 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 your area.

A way of figuring out when it's possible to plant lunaria is to look at the USDA zone info for Gardner.

Planting Calendar for Lunaria

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

Lunaria do well in moderate cold which means that you can plant them just a bit earlier in the year than other frost tender plants.

The earliest that you can plant lunaria in Gardner 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 lunaria and expect a good harvest is probably September. You probably don't want to wait any later than that or else your lunaria may not have a chance to fully mature. If you are starting your lunaria indoors then you might be able to get away with starting them a couple of weeks earlier.
