One of the first steps you take when you are figuring out your gardening schedule is find your 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.

You can determine when it's possible to plant brachycome in Zone 6a by reviewing the USDA zone info.

Planting Calendar for Brachycome

Since brachycome are not cold tolerant you really should wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant brachycome in Zone 6a 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 brachycome and expect a good harvest is probably August. Any later than that and your brachycome may not have a chance to really do well. If you are starting your brachycome indoors then you might be able to get away with starting them a couple of weeks earlier.
