The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Geneseo you can figure out when you can plant primula by referring to the USDA zone info.

Primula do well in cold which tells us that you can plant them a quite a bit earlier than other plants that might not handle the cold.

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