Understanding some facts about frosts may help prolong your gardening season, and help to protect your plants from injury.
The most common question concerns frost dates. Generally, and this will vary with area, the first frost date in fall in USDA hardiness zone 5 is around the first week of October, about 10 days earlier in zone 4.

These zones refer to average annual minimum temperatures, and are shown on a map seen in many publications (www.usna.usda.gov).
