The first frost can damage unprotected plants and signal the end of the growing season for outdoor gardens. Homeowners should be prepared to bring potted plants indoors and cover sensitive vegetation. Frost also serves as a reminder to winterize vehicles and outdoor equipment. In northern Minnesota, frost may arrive earlier, increasing the urgency for seasonal preparations. While frost itself is not hazardous, it often precedes colder weather that can bring icy conditions and other winter-related challenges.
