*These gardening tips are applicable for an average year in the southeastern New York region: USDA Plant Hardiness Zones 6a and 6b, which include New York City, Northern New Jersey, Rockland County, Westchester County, Southern Connecticut, and parts of Long Island. Plant hardiness zones refer to geographic areas where the growing season of plants is determined by the time of killing frosts in the spring and fall. Even within zones, climatic factors such as altitude, proximity to water, wind exposure, winter sun exposure and snow cover contribute to the existence of different "microclimates" and can influence plant adaptability.
