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

A common way of determining when you can plant bachelor buttons is to look at the USDA zone info for Mexico.

The last month that you can plant bachelor buttons and expect a good harvest is probably September. You probably don't want to wait any later than that or else your bachelor buttons may not have a chance to fully mature.
