Frost dates refer to the average dates when temperatures drop to 32°F (0°C), which can damage or kill tender plants. By knowing these dates, you can protect your plants and optimize your gardening efforts.

• First Fall Frost Date: The average date of the first frost in fall.

Knowing these dates helps gardeners determine the length of the growing season and plan accordingly.
