According to the Asthma and Allergy Foundation of America, about 75% of Americans who have plant allergies are sensitive to ragweed. You’ll find common ragweed sprouting in the fields and roadsides, riverbanks, and throughout rural areas. Ragweed pollen season begins in mid-summer and continues through the middle of November. Species of ragweed account for most of the hay fever reactions experienced in the fall months. Symptoms include sneezing and runny nose, as well as itchy eyes.

Ragweed pollen is most prevalent from August through November.

Ragweed Allergy Information

Ragweed is a common plant that grows throughout North America and Europe. Its scientific name is Ambrosia artemisiifolia, and it belongs to the sunflower family. The peak ragweed season in the United States typically occurs in late summer and early fall, usually from mid-August until the first frost. The exact timing of peak season can vary depending on factors such as location, weather patterns, and altitude. 

Ragweed pollen is very light and can be carried long distances by the wind. This is why ragweed allergies can be a problem even in areas where the plant is not present. Ragweed pollen counts tend to be highest in the morning, and on hot, dry, and windy days.

Ragweed is most prevalent in the central and eastern regions of the United States, particularly in areas with warm and dry climates. It is commonly found in the Midwest and in the southern states, including Texas, Oklahoma, Arkansas, Louisiana, and Mississippi. However, ragweed can grow in many parts of the country, and its pollen can be carried by the wind over long distances, so it can cause allergies in people who live outside of these areas as well.

If you suspect that you are allergic to ragweed or other weeds and grasses, we strongly recommend coming in for an allergy test!
