Gardeners who stop watering their plants after the first frost may inadvertently harm cold-tolerant plants. While the first frost signals the arrival of colder weather, it does not mean that plants are completely dormant. Roots remain alive underground, and dry soil can lead to damage or stress for plants. Overwatering, however, can also pose risks, especially if water collects on foliage before freezing temperatures, potentially causing harm to the plants. Proper watering techniques and timing are essential to ensure plant health during the colder months.
