Half the years, the last spring night at 32°F comes before May 7, so plant tender crops after that date or wait a week or two to be safer. Fall color depends on the trees, but the US Department of Agriculture says the brightest leaves come with warm, sunny days and cool nights, and that frost ruins vivid color. Here, cool 36°F nights usually start around September 28 and the first frost comes around October 5.
