Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Zone 6b. In the coldest months of winter we can expect an average low temperature of -5°F.

Just be sure to remember that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 6b and it is different every year. Half of the time in Zone 6b there is a last frost after April 15 so always be ready to protect your flax in the event of one of those late frosts.
