What Causes Fall Allergies?

Many people are allergic to the pollen from the ragweed plant. Typically, ragweed begins to release its pollen during August and may continue to release pollen into September and October. Approximately 75% of people who suffer allergies from spring plants are also allergic to ragweed.


Ragweed plants are abundant and diverse throughout North America. You’re most likely to find ragweed growing along the road, in vacant lots, and in other open areas. A single ragweed plant may produce one billion pollen grains each fall.

Even if you live in a region where ragweed growth is limited, you may still suffer from ragweed allergies. With a strong wind, ragweed pollen may travel up to 400 miles. Some people who are allergic to ragweed also experience allergy symptoms when they eat certain types of fruits and vegetables, including zucchini, melon, and bananas.


Mold growth appears in early spring and thrives through the first frost. When most people think of mold growth, they think about the growth that may occur in the damp areas of the home, such as bathrooms and the basement. However, mold spores also seek out wet spots outdoors. In the fall, piles of damp leaves provide the perfect breeding grounds for mold spores. You may also find mold in the soil and in compost piles.
