The cool-season window in Detroit starts at late-May, when nights stop freezing — think kale, peas, spinach, and parsnips. In Detroit, warm-season transplants — tomatoes, peppers, basil — wait two weeks past Detroit's frost date. It shuts near early-October, when freezes return to Detroit and tender plants need cover. Within Detroit, cold-air pooling chills low spots by 5-10°F, shifting Detroit's local frost dates.

Red-winged blackbirds return to Detroit's wetlands in late March, with males arriving first to claim territory among the emerging cattails.
