Trees run from March into May, later near the big lakes. This month sits outside the usual tree pollen window for the Midwest & Great Lakes pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Indiana allergy season guide singles out ragweed above all — the state’s defining allergen — over a maple, elm and oak spring.
