When can I plant Lunaria in Zone 2b

One of the best tools that we have as gardeners to help us figure out 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.

One way of getting a good idea when it's the best time to plant lunaria is to examine the USDA zone info for Zone 2b.

The earliest that you can plant lunaria in Zone 2b is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant lunaria and expect a good harvest is probably August. 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.

Last Frost Date
