Answer: You are near the edge of zones 5 and 6; the zones are based on average winter low temperature and so the microclimate in your garden can affect it. If your garden is very windy, for example, plan for zone 5. If it is sheltered and in town, plan for zone 6. There may also be individual locations within your yard that are significantly warmer or colder than others. You may also find that you are in a frost pocket and often have frost later in the spring and earlier in the fall than your neighbors. This can have an effect on seeds planted outdoors.
