Cedar Rapids Pollen Report
Cedar Rapids sits in the heart of Iowa's farm belt — a landscape that produces corn, soybeans, and an enormous amount of grass and ragweed pollen. Oak and maple drive the spring, pasture grasses carry the summer, and fall brings some of the heaviest ragweed counts in the Midwest. It's a demanding allergy calendar.
