Growing vegetables in Zone 1 areas can be challenging due to the harsh cold and frequent frosts. Understanding the frost tolerance of different vegetables is essential to ensure a successful harvest and healthy plants.
What Is Frost Tolerance?
Frost tolerance refers to a plant’s ability to survive and even thrive after exposure to freezing temperatures. Some vegetables can withstand light frosts, while others require protection or must be planted after the last frost date.
Frost Tolerance Levels in Vegetables
- Very Tolerant: Can survive multiple frosts and cold temperatures below freezing.
- Tolerant: Can withstand light frosts but may suffer damage in severe cold.
- Intolerant: Sensitive to frost and should be planted after danger of frost has passed.
