One of the best tools that you have as gardeners to help us determine 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.

In Espanola you can determine when it's possible to plant primula by looking at the USDA zone info.

Since primula are very cold tolerant you can plant them a lot earlier in the year than more sensitive plants.
