Frost damage occurs when temperatures drop below freezing, causing ice crystals to form in plant tissues. This can lead to cell rupture, wilting, and discoloration, ultimately harming or killing the affected plants. Commonly affected plants include flowers, vegetables, and fruit trees. Frost damage is most likely to happen during late spring or early fall when temperatures can fluctuate. Gardeners can protect their plants by using methods such as covering them with cloth or moving potted plants indoors during cold snaps. Understanding frost damage helps in planning and maintaining healthy gardens.
